  IS31AP2010E integrated silicon solution, inc. ? www.issi.com 1 rev. 00a, 05/02/2012 mono filter-less class-d audio power amplifier advanced information may 2012 general description the IS31AP2010E is a high efficiency, mono filter-less class-d audio power amplifier. a low noise, filter-less pwm architecture eliminates the output filter, reduces external component count, system cost, and simplifying design. in cellular handsets, the earpiece, speaker phone, and melody ringer speaker can each be driven by the IS31AP2010E. the gain of IS31AP2010E is externally configurable which allows independent gain control from multiple sources by summing signals from each function. IS31AP2010E is available in utqfn-9 packages . it operates from 2.7v to 5.5v over the temperature range of -40c to +85c. features ? supply voltage from 2.7v ~ 5.5v ? high efficiency ? less than 1 a shutdown current ? optimized pwm output stage eliminates lc output filter ? fully differential design reduces rf rectification and eliminates bypass capacitor ? improved cmrr eliminates two input coupling capacitors ? integrated click-and-pop suppression circuitry ? utqfn-9 package ? rohs compliant and 100% lead(pb)-free applications ? wireless or cellular handsets and pdas ? portable dvd player ? notebook pc ? portable radio ? educational toys ? portable gaming typical application circuit out+ gnd IS31AP2010E b1,b2 a3 c3 vcc out- c s 1 f v battery c1 in- in+ a1 0.1 f a2,b3 sdb c2 100k c in+ 0.1 f c in- 0.1 f r in+ 150k r in- 150k differential input shutdown control figure 1 typical application circuit (differential input) http://www..net/ datasheet pdf - http://www..net/
