General Description
G1430 is a stereo audio power amplifier in 16pin Dual
Inline Package. It can drive 1.8W continuous RMS
power into 4⦠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 sim-
plify the audio system design in the notebook applica-
tion, G1430 supports the Bridge-Tied Load (BTL)
mode for driving the speakers, Single-End (SE) mode
for driving the headphone. For the low current con-
sumption applications, the SHDN mode is supported
to disable G1430 when it is idle. The current consump-
tion can be further reduced to below 5µA.
