G1454/G1454L

2.0W Stereo Audio Amplifier with Shutdown Mode

Features

General Description

Depop Circuitry Integrated

The G1454/G1454L is a stereo audio power amplifier

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

can drive 1.45W 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 G1454/G1454L 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, VCC=5V

--2.1W (typical) into a 3Ω Load

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

--1.45W (typical) into a 4Ω Load

--1.15W (typical) into a 8Ω Load

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

--2W (typical) into a 4Ω Load

--1.47W (typical) into a 8Ω Load

Stereo Bridge-Tied Load (BTL)

Shutdown Control Available

Giving the SHUTDOWN pin low level will drive the

G1454L entering the shutdown.

TQFN3X3-16 Package Available

Giving the SHUTDOWN pin high level will drive the

G1454 entering the shutdown
