Description
The TS4962M is a differential Class-D BTL power
amplifier. It is able to drive up to 2.3W into a 4
Ω
load and 1.4W into a 8
Ω load at 5V. 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 & 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.
Applications
■ Cellular phone
■ PDA
■ Notebook PC
