Description
The TS4962 is a differential class-D B.T.L. power amplifier. Able to drive up to 2.3W into a 4 load and 1.4W into a 8 load at 5V. It achieves outstanding efficiency (88%typ.) compared to classical AB-class audio amps. 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 to lower the current consumption to 10nA typ.

2 Application Component Information
Component Cs Rin Input Capacitor Functional Description Bypass supply capacitor. To install as close as possible of the TS4962 to minimize high frequency ripple. A 100nF ceramic capacitor should be add to enhance the power supply filtering in high frequency. Input resistor to program the TS4962 differential gain (Gain = 300k/Rin with Rin in k) Thanks to common mode feedback, these input capacitors are optional. However, we can add then to form with Rin a 1st order high pass filter with -3dB cut-off frequency = 1/(2**Rin*Cin)
