max4298/max4299 ultra-high psrr stereo drivers + microphone amp + 100ma linear regulators _______________________________________________________________________________________ 7 detailed description the max4298/max4299 are audio system ics de- signed for single +5v applications. the max4299 has a stereo headphone driver, a microphone amplifier, and a 100ma +3.3v linear regulator; the max4298 has the stereo headphone driver only. the max4298/max4299 are designed specifically for harsh digital environments where board space is at a premium and the digital power supply is noisy. the design uses innovative design techniques to achieve ultra-high power-supply rejection across the audio signal band while, at the same time, delivering a high current rail-to-rail output drive capability. these devices are designed to drive highly capacitive loads that may be encountered when driving long cables to a remote load such as desktop/notebook headphones or speakers. they are fully compliant to pc99 standards. figure 1 is the max4298 block diagram and figure 2 is the max4299 block diagram. the amplifiers exhibit better than 115db of dc power- supply rejection and 93db at 20khz. the output ampli- fiers are capable of driving a 1.5v rms signal into 10k ? load with 0.0008% distortion. they can also drive 32 ? headphones to 1.2v rms with 0.02% distortion. at +3.3v, the linear regulator can output 100ma of current. the max4298 is available in a 10-pin max package; the max4299 is available in a 16-pin tssop package. pin description name max4298 max4298 max4299 pin 10-pin max 14-pin so 16-pin tssop/so function reg 1 regulator output. bypass reg to gnd with a 10f capacitor. fb 2 regulator feedback. internal resistors from this point to reg and gnd define the regulator output value. adjustments can be made to the output value by adding resistors in the same place externally. out1 1 2 3 driver amplifier output gnd 2 3 4 ground in1 3 4 5 inverting input for driver amplifiers bias 4 5 6 bias point for amplifiers. bypass bias to gnd with a 1f capacitor. sv cc 567 standby power supply. connect to a standby +5v supply that is always on, or bypass with 220f and connect a schottky diode from v cc to sv cc . short to v cc if clickless power-down is not essential. micout 8 microphone amplifier output micin 9 inverting input for microphone amplifier mute 6 9 10 mute digital input. connect to gnd for normal operation. when mute is connected to v cc , out1 and out2 are muted, reg stays on, and micout stays on. c bypass 7 10 11 bypass to gnd with a 1f capacitor. in2 8 11 12 inverting input for driver amplifier out2 9 12 13 driver amplifier output v cc 10 13 14 power supply. connect to +5v. n.c. 1, 7, 8, 14 15 no internal connection. regon 16 regulator control. connect to v cc for normal operation. connect to gnd to shut off the regulator.
max4298/max4299 ultra-high psrr stereo drivers + microphone amp + 100ma linear regulators 8 _______________________________________________________________________________________ bias the common-mode bias point for the amplifiers is set to 2.25v by internal circuitry that has two functions. it pro- vides a clickless/popless power-up/power-down wave- form for the amplifiers. also, it generates a ground-referenced bias voltage with ultra-high power- supply rejection ratio (psrr). bias should be bypassed with 1f to gnd.the output impedance of the bias pin is 50k ? . clickless/popless function the max4298/max4299 are designed for high-fidelity audio performance into ac-coupled loads. patented design techniques achieve a clickless/popless power-up sequence, and the use of a low-current standby supply (sv cc ) or external schottky diode/reservoir capacitor combination allows clickless/popless power-down. a clickless/popless mute function is also provided to main- tain a low impedance output when the input signal is switched off. mute function the max4298/max4299 have a mute pin that allows the user to mute the outputs of the device. this feature dis- connects the input signal from the power amplifiers when a logic high is present at the mute pin. to ensure proper functionality, the mute pin should always be tied to either v cc or gnd. mute only affects the headphone driver outputs. reg, bias, and micout are unaffected. out1 and out2 are muted, but remain in a low impedance state to ensure clickless/popless operation. sv cc the max4298/max4299 provide a fully clickless power- down sequence. sv cc can either be connected to a low- current +5v power source or alternatively can be connected with a reservoir capacitor to ground and a schottky diode to v cc . a reservoir capacitor of 220f or higher provides enough charge for the clickless power- down sequence when c bias = 1f. for larger values of c bias , increase the reservoir capacitor accordingly. short to v cc if clickless power-down is not needed. driver amplifier the headphone driver amplifier is a class ab amplifier designed to drive 16 ? loads. the amplifiers have innov- ative architectures for both the input and output stages to achieve ultra-high psrr while maintaining rail-to-rail output drive capability. the output stage can drive high capacitive loads encountered when driving long cables used for desktop speakers or headphones. microphone preamplifier (max4299) the max4299 provides a microphone preamplifier that is a low-power version of the audio amplifier. it is intend- ed to be used for low-level signal amplification. this microphone preamplifier provides rail-to-rail output with very high psrr. regulator (max4299) the max4299 also has an additional 100ma low- dropout (ldo) regulator to provide clean analog power for other sensitive analog circuitry on the pc board, such as a typical pc99 audio codec or microphone max/so c bypass in1 v cc sv cc out1 mute out2 gnd max4298 in2 v bias + _ + _ 50k ? 2.25v figure 1. max4298 block diagram tssop c bypass out1 micin gnd max4299 micout mute in2 bias in1 1.233v fb v cc sv cc regon reg 18.4k ? 11k ? 50k ? out2 n.c. + _ 2.25v + _ + _ + _ figure 2. max4299 block diagram
