G1426
Global Mixed-mode Technology Inc.
2.5W Stereo Audio Amplifier
General Description
Features
Depop Circuitry Integrated
The G1426 is a stereo audio power amplifier in 20pin
TSSOP package. It can deliver 2W continuous RMS
power into 4Ω load per channel in Bridge-Tied Load
(BTL) mode at 5V supply voltage under 1% THD. To
simplify the audio system design in the notebook ap-
plication, The G1426 supports the Bridge-Tied Load
(BTL) mode for driving the speakers. For the low cur-
rent consumption applications, the SHDN mode is
supported to disable the G1426 when it is idle. The
current consumption can be further reduced to below
2µA.
Output Power at 10% THD+N, VDD=5V
--2.5W/CH (typical) into a 4Ω Load
Output Power at 1% THD+N, VDD=5V
--2W/CH (typical) into a 4Ω Load
--1.2W/CH (typical) into a 8Ω Load
