Preliminary Datasheet
Filterless 6W Class- F Mono Audio Amplifier
LPA2176
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.
