General Description
The G1442 is a mono audio power amplifier in 8 pin
SOP-8, MSOP-8, SOP-8 (FD) or TDFN3X3-8 with
thermal pad package. It can drive 2W continuous RMS
power into 4Ω load in Bridge-Tied Load (BTL) mode at
5V supply voltage. Its THD is smaller than 1% under
the above operation condition. For the low current con-
sumption applications, the SHDN mode is supported
to disable the G1442 when it is idle. The current con-
sumption can be further reduced to below 1µA.
Giving the SHUTDOWN pin low level will drive the
G1442 entering the shutdown.
