8W Mono Class- F Audio Amplifier With EQ Function

General Description

The LPA2173 is a 8W, class-F audio amplifier with a mode pin for switch the work mode. 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 LPA2173 is available in ESOP-8.

Applications

Portable Bluetooth Speaker

Cellular and Smart mobile phone
