Features
Description
The TS4962 is a differential class-D BTL power
amplifier. It is able to drive up to 2.2W into a 4Ω
load and 1.4W into a 8Ω 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) allows the reduction
of current consumption to 10nA typ.
