General Description
G1431 is a stereo audio power amplifier in 20pin TSSOP thermal pad package or 20-pin TQFN 4X4. It can drive 2W continuous RMS power into 4Ω load per channel in Bridge-Tied Load (BTL) mode at 5V supply voltage. Its THD is smaller than 1% under the above operation condition. To simplify the audio system design in the notebook application and to enlarge the driving power, G1431 supports the Bridge-Tied Load (BTL) mode for driving the speakers. For the low current consumption applications, the SHDN mode is supported to.
