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.
