General Description
G1420 is a stereo audio power amplifier in 24pin
TSSOP thermal pad package. It can drive 1.8W con-
tinuous RMS power into 4
Ω 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 5A.
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.
