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.
