TS4962IQT

TS4962IQT is a 2.8W filter-free mono class D audio power amplifier in a 8 pin DFN package. The TS4962 is a differential class-D BTL power amplifier. It can drive up to 2.2W into a 4ohm load and 1.4W into an 8ohm load at 5V. 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 5ms. A standby function (active low) enables the current consumption to be reduced to 10nA typical. Typical applications include cellular phones, PDAs, notebook PCs.
