General Description
The G1901 is a mono class-D audio power amplifier in
MSOP-10 (FD), TDFN3X3-10 and WLCSP3X3-9 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
consumption applications, the SHDN mode is sup-
ported to disable the G1901 when it is idle. The cur-
rent consumption can be further reduced to below
1µA.
Giving the SHUTDOWN pin low level will drive the
G1901 entering the shutdown.
