Description

The TS2012 is a fully differential stereo class D

power amplifier able to drive up to 1.15 W into an

8 Ω load at 5 V per channel. It achieves better

efficiency compared to typical class AB audio

amps.

The device has four different gain settings utilizing

2 digital pins: G0 and G1.

Pop and click reduction circuitry provides low

on/off switch noise while allowing the device to

start within 8 ms.

Two standby pins (active low) allow each channel

to be switched off separately.

The TS2012 is available in a flip-chip 16-bump

lead-free package.
