2.6W Mono Audio Amplifier with Shutdown Mode

Features

General Description

Depop Circuitry Integrated

The G1442 is a mono audio power amplifier in 8 pin

SOP-8, MSOP-8, SOP-8 (FD) or TDFN3X3-8 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 con-

sumption applications, the SHDN mode is supported

to disable the G1442 when it is idle. The current con-

sumption can be further reduced to below 1µA.

2.7V 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

Mono Bridge-Tied Load (BTL)

Shutdown Control Available

SOP-8, MSOP-8, SOP-8 (FD) and TDFN3X3-8

Package Available

Giving the SHUTDOWN pin low level will drive the

G1442 entering the shutdown.
