G1453/G1453L Global Mixed-mode Technology Inc. 2.6W Stereo Audio Amplifier with Shutdown Mode Features General Description Depop Circuitry Integrated 3V to 5.5V Operation Output Power at 10% THD+N, VDD=5V --2.6W (typical) into a 3Ω Load Output Power at 1% THD+N, VDD=5V --2W (typical) into a 4Ω Load --1.3W (typical) into a 8Ω Load Stereo Bridge-Tied Load (BTL) Shutdown Control Available TQFN3X3-16 Package Available 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. Giving the SHUTDOWN pin low level will drive the G1453L entering the shutdown. Applications Giving the SHUTDOWN pin high level will drive the G1453 entering the shutdown PDAs Portable Devices Notebook Ordering Information ORDER NUMBER MARKING TEMP.
