IS31AP2031
DESCRIPTION
The IS31AP2031 is a Class-G audio power amplifier with automatic gain control. It drives up to 2.0W (10% THD+N) into an 8Ω speaker from a 4.2V VDD supply. The IS31AP2031 provides low cost, space saving solution for portable equipments which need audio output with higher power by boosting up supply voltage. Its external ponents just include a few capacitors and resistors (no inductor). The IS31AP2031 use fully differential design to reduce RF noise. The IS31AP2031 integrates de-pop circuitry to reduce pop and click noise during power on/off or shutdown enable operation. The IS31AP2031 also integrates thermal and short circuit protection function. IS31AP2031 is available in QFN-20 (3mm × 3mm) package. It operates from 2.7V to 4.5V over the temperature range of -40°C to +85°C. FEATURES
