Features
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 supported to disable the G1901 when it is idle. The current consumption can be further reduced to below
1µA.
