G1432  
2W Stereo Audio Amplifier  
Features  
General Description  
„
Depop Circuitry Integrated  
The G1432 is a stereo audio power amplifier in 24pin  
TSSOP thermal pad package or 24pin QFN package.  
It can drive 1.8W 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  
--1.8W/CH (typical) into a 4Ω Load  
--1.2W/CH (typical) into a 8Ω Load

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  
Applications  
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.
