LPA2176 2.5-5.5 Class AB/D 3W,5V@4Ω,10% 1 -70 X Y 2 ESOP8

Filterless 6W Class- F Mono Audio Amplifier integrated Non-Crack Noise function

General Description

The LPA2176 is a 6W, class-F mono audio amplifier integrated Class AB/D optional mode and unique Non-Crack Noise (NCN) function. It is capable of delivering 6.6watts of continuous average power to a 2Ω BTL load with less than 10% distortion (THD) from a 5.5V DC power supply. It offers low THD+N, allowing it to achieve high-quality Power Supply sound reproduction. The new filterless architecture allows the device to drive the speaker directly requiring no low-pass output filters, thus to save the system cost and PCB area. The LPA2176 is available in ESOP-8.
