Description

The TS2007FC is a class D power audio

amplifier. Able to drive up to 1.4 W into an 8 Ω

load at 5 V, it achieves better efficiency than

typical class AB audio power amplifiers.

This device can switch between two gain settings,

6 dB or 12 dB via a logic signal on the gain select

pin. Pop and click reduction circuitry provides low

on/off switch noise and allows the device to start

within 1 ms typically.

A standby mode function (active low) keeps the

current consumption down to 1 μA typical.

The TS2007FC is available in a 9-bump flip-chip

lead-free package.
