无滤波立体声2 x 2.8W D类音频功率放大器




The TS2012EI 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 two 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 TS2012EI is available in a Flip Chip 16 bump lead-free package.
