Description

The TS2012 is a fully differential, class D, power

amplifier stereo. It is able to drive up to 1.35 W

into an 8

Ω load at 5 V per channel. It achieves

outstanding efficiency compared to typical class

AB audio amps.

The device has four different gain settings utilizing

two discrete pins: G0 and G1.

Pop and click reduction circuitry provides low

on/off switch noise while allowing the device to

start within 1 ms.

Two standby pins (active low) allow each channel

to be switched off independently.

The TS2012 is available in a QFN20 4x4 mm

package.
