Description
The TS2012 is a stereo fully differential class D
power amplifier. Able to drive up to 1.35W into an
8
Ω load at 5V 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 & click reduction circuitry provides low on/off
switch noise while allowing the device to start
within 1ms.
Two standby pins (active low) allow each channel
to be switched off independently.
The TS2012 is available in a QFN20 package in
4x4 mm dimension.
