Description
Block Diagram
The TS4962 is a differential class-D B.T.L. power
amplifier. 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 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.

Functional Description
Bypass supply capacitor. To install as close as possible of the TS4962 to minimize high frequency rip-
ple. A 100nF ceramic capacitor should be add to enhance the power supply filtering in high frequency.

Rin
Input resistor to program the TS4962 differential gain (Gain = 300kΩ/Rin with Rin in kΩ)
Input
Capacitor
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*π*Rin*Cin)

1) Standby mode is actived when Vstdby is tied to GND.
2) Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc @ f = 217Hz.
