BL6203 - 1.25 Watt Fully Differential Audio Power Amplifier

General Description

The BL6203 is a fully differential audio power amplifier designed for portable communication device applications.

It is capable of delivering 1.25 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V battery voltage.

It operates from 2.2 to 5.5V.
