Global Mixed-mode Technology Inc.

2.6W Stereo Audio Amplifier

General Description

G1432

Features

Depop Circuitry Integrated

The G1432 is a stereo audio power amplifier in 24pin

TSSOP thermal pad package or 24pin QFN package.

It can drive 2.0W continuous RMS power into 4Ω load

per channel in Bridge-Tied Load (BTL) mode at 5V

supply voltage. Its THD is smaller than 1% under the

above operation condition. The G1432 can mute the

output when Mute is activated. For the low current

consumption applications, the SHDN mode is sup-

ported to disable the G1432 when it is idle. The cur-

rent consumption can be further reduced to below

5µA.

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

--2.0W/CH (typical) into a 4Ω Load

--1.3W/CH (typical) into a 8Ω Load

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

--2.6W/CH (typical) into a 4Ω Load

--1.6W/CH (typical) into a 8Ω Load

Maximum Output Power Clamping Circuitry

Integrated

Bridge-Tied Load (BTL)

Stereo Input MUX

Mute and Shutdown Control Available

Surface-Mount Power Package

24-Pin TSSOP-P & 24-Pin QFN Available

The G1432 also supports two input paths, that means

two different gain loops can be set in the same PCB

and choosing either one by setting IN1/IN2 pin. It en-

hances the hardware designing flexibility. The G1432

also supports an extra function -- the maximum output

power clamping function to protect the speakers from

burned-out.
