1. Caution: This device is not protected in the event of abnormal operating conditions such as, for example, short-circuiting between any one output pin and ground, between any one output pin and VCC, and between individual output pins.
2. All voltage values are measured with respect to the ground pin.
3. The magnitude of the input signal must never exceed VCC + 0.3V / GND - 0.3V.
4. Exceeding the power derating curves during a long period will provoke abnormal operation.
5. The magnitude of the standby signal must never exceed VCC + 0.3V / GND - 0.3V.




Description

The TS4962 is a differential class-D BTL power amplifier. It is able to drive up to 2.2W into a 4 load and 1.4W into a 8 load at 5V. It achieves outstanding efficiency (88% typ.) compared to standard AB-class audio amps.

The gain of the TS4962 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.
