Description

The TS4962M is a differential Class-D BTL power

amplifier. It is able to drive up to 2.3 W into a 4 Ω

load and 1.4 W into a 8 Ω load at 5 V. It achieves

outstanding efficiency (88% typ.) compared to

classical Class-AB audio amps.

The gain of the device can be controlled via two

external gain-setting resistors. Pop and click

reduction circuitry provides low on/off switch

noise while allowing the device to start within

5 ms. A standby function (active low) allows the

reduction of current consumption to 10 nA typ.
