samhop microele ctronics corp. page 1 general description the SM7511 is a stereo audio power amplifier that drives 3 w/channel of continuous rms power into a 3- ? load. advanced dc volume control minimizes external components and allows btl (speaker) volume control and se (headphone) volume control. notebook and pocket pcs benefit from the integrated feature set that minimizes external components without sacr ificing functionality. to simplify design, the speaker volume level is adjusted by applying a dc voltage to the volume terminal. likewise, the delta between speaker volume and headphone volume can be adjusted by applying a dc voltage to the sediff terminal. to avoid an unexpected high volume level through the headphones, a third terminal, semax, limits the headphone volume level when a dc voltage is applied. finally, to ensure a smooth transition between active and shutdown modes, a fade mode ramps the volume up and down. features * advanced dc volume control with 2-db steps from -40 db to 20 db - fade mode - maximum volume setting for se mode - adjustable se volume control referenced to btl volume control * 3 w into 3 - ? speakers * stereo input mux * differential inputs applications * notebook pc * lcd monitors * pocket pc * portable dvd * mini speaker pin assignments (top view) rout+ se/btl hp/line volume sediff semax agnd bypass fade shutdown lout+ pgnd pgnd rout- pv dd rhpin rlinein rin v dd lin llinein lhpin pv dd lout- SM7511 24pin 124 223 322 421 520 619 718 817 916 10 15 11 14 12 13 thermal pad v.1.3 revised april 02,2007 3w stereo audio power amplifier with advanced dc volume control

samhop microelectronics corp. 3w stereo audio power amplifier with advanced dc volume control page 10 the ability of the SM7511 to easily switch between btl a nd se modes is one of its most important cost saving features. this feature eliminates the requirement fo r an additional headphone amplifier in applications where internal stereo speakers are driven in btl mode but external headphone or speakers must be accommodated. internal to the SM7511, two separate amplifiers drive out+ and out-. the se/btl input controls the operation of the follower amplifier that drives lout- and rout-. when se/btl is held low, the amplifier is on and the SM7511 is in the btl mode. when se/btl is held high, the out- amplifiers are in a high output impedance state, which configures the SM7511 as an se driver from lout+ and rout+. i dd is reduced by approximately one-third in se mode. control of the se/btl input can be from a logic-leve l cmos source or, more typically, from a resistor divider network as shown in figure 3. the trip level for the se/btl input can be found in the recommended operating condition table. using a 1/8-in. (3,5mm) stereo headphone jack, the control switch is closed when no plug is inserted. when closed the 100k ? /1k ? divider pulls the se/btl input low. when a plug is inserted, the 1k ? resistor is disconnected and se/btl input is pulled high. when the input goes high, the out- amplifier is shut down causing the speaker to mute (open-cir cuits the speaker). the out+ amplifie r then drives through the output capacitor (c o ) into the headphone jack. se/btl operation application information (continued) rhpin + _ rout+ rout- rlinein rin + _ + _ se/btl r mux hp/line _ + byp input mux control byp en byp 24 2 23 100k ? 100k ? v dd co 330 f 1k ? lout+ 4 5 22 6 figure 3.

samhop microelectronics corp. 3w stereo audio power amplifier with advanced dc volume control page 12 after the channel gain is stepped down to the lowest gain, the amplifier begins discharging the bypass capacitor from the nominal voltage of v dd / 2 to ground. this time is dependent on the value of the bypass capacitor. for a 0.47 f capacitor that is used in the application diagr am in figure 1, the time is approximately 500 ms. this time scales linearly with the val ue of bypass capacitor. for example, if a 1 f capacitor is used for bypass, the time period to discharge the capacitor to ground is twice that of the 0.47 f capacitor, or 1 seconds. figure 3 below is a waveform captured at the output during the shutdown sequence when the part is in fade-on mode. the gain is set to the highest level and the output is at v dd when the amplifier is shut down. when a logic high is placed on the shutdown pin and the fade pin is still held low, the device begins the start-up process. the bypass capacitor will begin charging . once the bypass voltage reaches the final value of v dd /2, the gain increases in 2 db steps from the lowest gain level to the gain level set by the dc voltage applied to the volume, sed iff and semax pins. in the fade-off mode, the amplifier stores the gain value prior to starting the shutdown sequences. the output of the amplifier immediately drops to v dd /2 and the bypass capacitor begins a smooth discharge to ground. when shutdown is released, the bypass capacitor charges up to v dd /2 and the channel gain returns immediately to the value stored in memory. figure 4 below is a wa veform captured at the output during the shutdown sequence when ths part is in the fade-off mode. the gain is set to the highest level, and the output is at v dd when the amplifier is shut down. the power-up sequence is different from the shutdow n sequence and the voltage on the fade pin does not change the power-up sequence. upon a power-up condition, the SM7511 begins in the lowest gain setting and steps up 2 db every 2 clock cycles unti l the final value is reac hed as determined by the dc voltage applied to the volume, sedi ff and semax pins. volume, sediff and semax operation three pins labeled volume, sediff and semax control th e btl volume when driving speakers and the se volume when driving headphones. all of these pins are co ntrolled with a dc voltage, which should not exceed v dd . when driving speakers in btl mode, the volume pin is the only pin that controls the gain. table 1 shows the gain for the btl mode. the voltage listed in the table are for v dd =5v. for a different v dd , the values in the table scale linearly. if v dd =4v, multiply all the voltages in the table by 4v/5v or 0.8. figure 5. shutdown sequence in the fade-off mode figure 4. shutdown sequence in the fade-on mode v.1.3 revised april 02,2007
samhop microelectronics corp. 3w stereo audio power amplifier with advanced dc volume control the SM7511 allows the user to specif y a difference between btl gain and se gain. this is desirable to avoid any listening discomfort when plugging in headphones. when switching to se mode, the sediff and semax pins control the single-ended gain proportional to the gain set by the voltage on the volume pin. when sediff =0v, the difference between the btl gain and t he se gain is 6db. as t he voltage on the sediff terminal is increased, the gain in se mode decreases. the voltage on the se diff terminal is subtracted from the voltage on the volume terminal and this value is used to determine the se gain. some audio systems require that the gain be limited in th e single-ended mode to a level that is comfortable for headphone listening. most volume control devices only have one terminal for setting the gain. for example, if the speaker gain is 20 db, the gain in the headphone channel is fixed at 14 db. the level of gain could cause discomfort to listeners and the semax pin allows the de signer to limit this disc omfort when plugging in headphones. the semax terminal controls the maximum gain for single-ended mode. the funtionality of the sediff and semax pin are comb ined to set the se gain. a block diagram of the combined funtionality is shown in figure 6. the value obtained from the block diagram for se_volume is a dc voltage that can be used in conjunction with table 2 to determine the se gain. again, the voltage listed in the table are for v dd =5v. the values must be sca led for other values of v dd . table 1 and table 2 show a range of voltages for each gain step. there is a gap in the voltage between each gain step. this gap represents the hysteresis about each trip point in the internal comparator. the hysteresis ensures that the gain control is monotonic and does not oscillate from one gain step to another. if a potentiometer is used to adjust the voltage on the contro l terminals, the gain increases as the potentiometer is turned in one direction and decreases as it is turned back the other direction. the trip point, where the gain actually changes, is different depending on whether the voltage is increased or decr eased as a result of the hysteresis about each trip point. the gaps in table 1 and table 2 can also be thought of as indeterminate states where the gain could be in the next higher gain step or the lower gain step depending on the direction the voltage is changing. if using a dac to control the volume, set the volume, set the voltage in the middle of each range to ensure that the desired gain is achieved. a pictorial representation of the volume control can be found in figure 7. the graph focuses on three gain steps with the trip points defined in table 1 for btl gain. the dotted line represents the hysteresis about each gain step. figure 6. block diagram of se volume control is semax> (volume-sediff)? volume-sediff + volume(v) yes se_volume(v)=volume(v)-sediff(v) semax(v) sediff(v) se_volume(v)=semax(v) page 13 v.1.3 revised april 02,2007
