2W Stereo Audio Amplifier

General Description

G1420

Features

^ꢀDepop Circuitry Integrated

^ꢀOutput Power at 1% THD+N, VDD=5V

--1.8W/CH (typical) into a 4Ω Load

--1.2W/CH (typical) into a 8Ω Load

^ꢀBridge-Tied Load (BTL), Single-Ended (SE)

^ꢀStereo Input MUX

G1420 is a stereo audio power amplifier in 24pin

TSSOP thermal pad package. It can drive 1.8W con-

tinuous RMS power into 4 load per channel in

Ω

Bridge-Tied Load (BTL) mode at 5V supply voltage. Its

THD is smaller than 1% under the above operation

condition. To simplify the audio system design in the

notebook application, G1420 supports the Bridge-Tied

Load (BTL) mode for driving the speakers, Single-End

(SE) mode for driving the headphone. G1420 can

mute the output when Mute-In is activated. For the low

current consumption applications, the SHDN mode is

supported to disable G1420 when it is idle. The cur-

rent consumption can be further reduced to below

5µA.

^ꢀMute and Shutdown Control Available

^ꢀSurface-Mount Power Package

24-Pin TSSOP-P

Applications

^ꢀStereo Power Amplifiers for Notebooks or

Desktop Computers

^ꢀMultimedia Monitors

G1420 also supports two input paths, that means two

different gain loops can be set in the same PCB and

choosing either one by setting HP/LINE pin. It en-

hances the hardware designing flexibility.
