2.6W Stereo Audio Amplifier with Shutdown Mode

Features

General Description

Depop Circuitry Integrated

The G1453/G1453L is a stereo audio power amplifier

in 16 pin TQFN3X3-16 with thermal pad package. It

can drive 2W continuous RMS power into 4Ω load in

Bridge-Tied Load (BTL) mode at 5V supply voltage. Its

THD is smaller than 1% under the above operation

condition. For the low current consumption applica-

tions, the SHUTDOWN mode is supported to disable

the G1453/G1453L when it is idle. The current con-

sumption can be further reduced to below 1µA.

3V to 5.5V Operation

Output Power at 10% THD+N, VDD=5V

--2.6W (typical) into a 3Ω Load

Output Power at 1% THD+N, VDD=5V

--2W (typical) into a 4Ω Load

--1.3W (typical) into a 8Ω Load

Stereo Bridge-Tied Load (BTL)

Shutdown Control Available

TQFN3X3-16 Package Available

Giving the SHUTDOWN pin low level will drive the

G1453L entering the shutdown.

Giving the SHUTDOWN pin high level will drive the

G1453 entering the shutdown
