2W Stereo Audio Amplifier

Features

General Description

Depop Circuitry Integrated

G1420 is a stereo audio power amplifier in 24pin

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

tinuous 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. 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 current

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

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

Stereo Input MUX

Mute and Shutdown Control Available

Surface-Mount Power Package

24-Pin TSSOP-P

Applications

Stereo Power Amplifiers for Notebooks or

Desktop Computers

G1420 also supports two input paths, that means two

different gain loops can be set in the same PCB and

Multimedia Monitors

Stereo Power Amplifiers for Portable Audio

Systems

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

hances the hardware designing flexibility.
