Global Mixed-mode Technology Inc. G1454/G1454L 2.0W Stereo Audio Amplifier with Shutdown Mode Features - Depop Circuitry Integrated - 3V to 5.5V Operation - Output Power at 10% THD+N, VCC=5V --2.1W (typical) into a 3Ω Load - Output Power at 1% THD+N, VCC=5V --1.45W (typical) into a 4Ω Load --1.15W (typical) into a 8Ω Load - Output Power at 10% THD+N, VCC=5V --2W (typical) into a 4Ω Load --1.47W (typical) into a 8Ω Load - Stereo Bridge-Tied Load (BTL) - Shutdown Control Available - TQFN3X3-16 Package Available Applications - PDAs - Portable Devices - Notebook 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...
