Global Mixed-mode Technology Inc. G1431 2W Stereo Audio Amplifier Features Internal Gain Control, Which Eliminates External Gain-Setting Resistors „ Depop Circuitry Integrated „ Output Power at 1% THD+N, VDD=5V --2.0W/CH (typical) into a 4Ω Load --1.2W/CH (typical) into a 8Ω Load „ Bridge-Tied Load (BTL) Supported „ Fully differential Input „ Shutdown Control Available www.DataSheet4U.com „ Surface-Mount Power Package 20-Pin TSSOP-P & 20-Pin TQFN 4X4 „ 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.
