Depop Circuitry Integrated Output Power at 10% THD+N, VDD=5V Output Power at 1% THD+N, VDD=5V
General Description
The G1426 is a stereo audio power amplifier in 20pin TSSOP package. It can deliver 2W continuous RMS power into 4Ω load per channel in Bridge-Tied Load (BTL) mode at 5V supply voltage under 1% THD. To simplify the audio system design in the notebook application, The G1426 supports the Bridge-Tied Load (BTL) mode for driving the speakers. For the low current consumption applications, the SHDN mode is supported to disable the G1426 when it is idle. The current consumption can be further reduced to below 2µA.
