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.
