TS4962：3W filter-free Class D audio power amplifier with active low standby mode
The TS4962 is a differential class-D BTL power amplifier. It can drive up to 2.2 W into a 4 Ω load and 1.4 W into an 8 Ω load at 5 V. It achieves outstanding efficiency (88% typ.) compared to standard AB-class 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 5 ms. A standby function (active low) enables the current consumption to be reduced to 10 nA typical.
