Filter-free stereo 2 x 2.8 W class D audio power amplifier

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.
