General Description
The G1454/G1454L is a stereo audio power amplifier in 16 pin TQFN3X3-16 with thermal pad package. It can drive 1.45W 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 G1454/G1454L when it is idle. The current consumption can be further reduced to below 1µA.
