_______________________________________________________________________________________ 9 MAX98306 stereo 3.7w class d amplifier detailed description the MAX98306 features low quiescent current, a low- power shutdown mode, comprehensive click-and-pop suppression, and excellent rf immunity. the ic offers class ab audio performance with class d efficiency in a minimal board-space solution. the class d amplifier features spread-spectrum modula - tion, active emissions limiting, edge-rate, and overshoot control circuitry that offers significant improvements to switch-mode amplifier radiated emissions. the amplifier also features click-and-pop suppression that reduces audible transients on startup and shut - down, as well as thermal-overload and short-circuit protection. class d speaker amplifier the filterless class d amplifier output stage offers much higher efficiency than class ab amplifiers. the high effi - ciency of a class d amplifier is due to the pulse-width modulated (pwm) rail-to-rail switching operation of the output stage transistors. this ensures that any power loss associated with the class d output stage is mostly due to the i 2 r loss of the mosfet on-resistance and quiescent current overhead. emi filterless output stage traditional class d amplifiers require the use of external lc filters, or shielding, to meet en55022b electromag - netic-interference (emi) regulation standards. maxims active-emissions-limiting edge-rate control circuitry and spread-spectrum modulation reduce emi emissions, while maintaining up to 92% efficiency. spread-spectrum modulation and active emissions limit - ing limit wideband spectral components, while propri - etary techniques ensure that the cycle-to-cycle varia - tion of the switching period does not degrade audio reproduction or efficiency. the ics spread-spectrum modulator randomly varies the switching frequency by q 20khz around the center frequency (320khz). above 10mhz, the wideband spectrum looks like noise for emi purposes (figure 1). speaker current limit if the output current of the speaker amplifier exceeds the current limit (3a typ), the ic disables the outputs for approximately 100 f s. at the end of 100 f s, the outputs are reenabled. if the fault condition still exists, the ic continues to disable and reenable the outputs until the fault condition is removed. selectable gain the ic offers five programmable gains selected using the gain input. shutdown the ic features a low-power shutdown mode, drawing p 1 f a (typ) of supply current. drive shdn low to place the MAX98306 into shutdown. drive shdn above 1.4v for normal operation. click-and-pop suppression the ic speaker amplifier features maxims comprehen - sive click-and-pop suppression. during startup, the click-and-pop suppression circuitry reduces any audible transient sources internal to the device. when entering shutdown, the differential speaker outputs ramp down to pgnd quickly and simultaneously. table 1. gain control configuration figure 1. emi with 12in of speaker cable and no output filter gain pin maximum gain (db) connect to pgnd 18 connect to pgnd through 100k i 5% resistor 15 connect to pvdd 12 connect to pvdd through 100k i 5% resistor 9 unconnected 6 frequency (mhz) emissions level (dbv/m) 900 800 600 700 200 300 400 500 100 0 10 20 30 40 50 60 70 80 90 -10 0 1000
10 _____________________________________________________________________________________ MAX98306 stereo 3.7w class d amplifier applications information filterless class d operation traditional class d amplifiers require an output filter. the filter adds cost and size and decreases thd perfor - mance. the ics filterless modulation scheme does not require an output filter. because the switching frequency of the ic is well beyond the bandwidth of most speakers, voice coil movement due to the switching frequency is very small. use a speaker with a series inductance > 10 f h. typical 8 i speakers exhibit series inductances in the 20 f h to 100 f h range. component selection power-supply input (pvdd) pvdd powers the speaker amplifier. pvdd ranges from 2.6v to 5.5v. bypass pvdd with 0.1 f f and 10 f f capaci - tors to pgnd. apply additional bulk capacitance at the device if long input traces between pvdd and the power source are used. input filtering the input-coupling capacitor (c in ), in conjunction with the amplifiers internal input resistance (r in ), forms a highpass filter that removes the dc bias from the incom - ing signal. these capacitors allow the amplifier to bias the signal to an optimum dc level. assuming zero source impedance, c in is: ? = in 3db in 1 c 2 f r where f -3db is the -3db corner frequency and r in is the typical value as specified in the electrical characteristics table. use capacitors with adequately low-voltage coeffi - cients for best low-frequency thd performance. table 2 shows calculated capacitance values based on a 20hz highpass filter. layout and grounding proper layout and grounding are essential for optimum performance. good grounding improves audio perfor - mance and prevents switching noise from coupling into the audio signal. use wide, low-resistance output traces. as the load impedance decreases, the current drawn from the device increases. at higher current, the resistance of the output traces decrease the power delivered to the load. for example, if 2w is delivered from the device output to a 4 i load through 100m i of total speaker trace, 1.904w is delivered to the speaker. if power is delivered through 10m i of total speaker trace, 1.99w is delivered to the speaker. wide output, supply, and ground traces also improve the power dissipation of the device. the ic is inherently designed for excellent rf immunity. for best performance, add ground fills around all signal traces on top or bottom pcb planes. chip information process: cmos table 2. capacitance value for 20hz highpass filter gain r in (k i ) c in for 20hz (nf) 18 33 241 15 46 173 12 65 122 9 93 86 6 131 61
