Features

1.1mW with BTL output


ROHM's monaural speaker amps, which uses a BTL output method to achieve 1.1mW of power at a supply voltage of 5V and a speaker load of 8W, are ideally suited for use in mobile devices such as mobile phones, PDAs, digital cameras, and digital video cameras. They feature low voltage operation (2.4V) and reduced power consumption and are available in a compact MSOP8 package, contributing to end-product miniaturization.

Selectable single/differential input

Reduces popping noise when the power supply is turned ON / OFF

TTL input compatibility allows direct connection to a 3.3V microcontroller (BH7826FVM)
