TS4962M3 W filter-free class D audio power amplifier
The TS4962M is a differential Class-D BTL power amplifier. It is able to drive up to 2.3W into a 4Ω load and 1.4W into a 8Ω load at 5V. It achieves outstanding efficiency (88%typ.) compared to classical Class-AB audio amps.
The gain of the device can be controlled via two external gain-setting resistors. Pop & click reduction circuitry provides low on/off switch noise while allowing the device to start within 5ms. A standby function (active low) allows the reduction of current consumption to 10nA typ.
- Operating from VCC= 2.4V to 5.5V
- Standby mode active low
