Description
The TS4962 is a differential class-D B.T.L. power
amplifier. Able to drive up to 2.3W into a 4
load
and 1.4W into a 8
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.
Applications
■ Cellular Phone
■ PDA
■ Notebook PC
