2.6W Stereo Audio Amplifier with Shutdown Mode
Features
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 applications, the SHUTDOWN mode is supported to disable
the G1453/G1453L when it is idle. The current consumption can be further reduced to below 1µA.
