1 / 13 page  IS31AP2010B Integrated Silicon Solution, Inc. – www.issi.com Rev.B, 04/10/2013 1 3W@5.0V MONO FILTER-LESS CLASS-D AUDIO POWER AMPLIFIER April 2013 GENERAL DESCRIPTION The IS31AP2010B is a high efficiency, 3W@5.0V 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. Operating in a single 5.0V supply, IS31AP2010B is capable of driving 4Ω speaker load at a continuous average output of 3W@10% THD+N. The IS31AP2010B has high efficiency with speaker load compared to a typical class- AB amplifier. In cellular handsets, the earpiece, speaker phone, and melody ringer speaker can each be driven by the IS31AP2010B. The gain of IS31AP2010B is externally configurable which allows independent gain control from multiple sources by summing signals from each function. IS31AP2010B is available in UTQFN-9 packages. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C. FEATURES 5.0V supply at THD+N = 10% ―3W into 4Ω (Typ.) ―1.68W into 8Ω (Typ.) Efficiency at 5.0V ―85% at 400mW with a 4Ω speaker ―88% at 400mW with an 8Ω speaker Less than 1μA 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 IS31AP2010B B1,B2 A3 C3 VCC OUT- CS 1 F VBattery C1 IN- IN+ A1 0.1 F A2,B3 SDB C2 100k CIN+ 0.1 F CIN- 0.1 F RIN+ 150k RIN- 150k Differential Input Shutdown Control Figure 1 Typical Application Circuit |
