General Description
The G1453/G1453L is a stereo audio power amplifier
in 16 pin TQFN3X3-16 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 applica-
tions, the SHUTDOWN mode is supported to disable
the G1453/G1453L when it is idle. The current con-
sumption can be further reduced to below 1µA.
Giving the
SHUTDOWN
pin low level will drive the
G1453L entering the shutdown.
Giving the SHUTDOWN pin high level will drive the
G1453 entering the shutdown
