G1430
2W Stereo Audio Amplifier
Features
Depop Circuitry Integrated Output Power at 1% THD+N, VDD=5V
General Description
G1430 is a stereo audio power amplifier in 16pin Dual Inline Package. It can drive 1.8W 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, G1430 supports the Bridge-Tied Load (BTL) mode for driving the speakers, Single-End (SE) mode for driving the headphone. For the low current consumption applications, the SHDN mode is supported to disable G1430 when it is idle. The current consumption can be further reduced to below 5µA.
--1.8W/CH (typical) into a 4Ω Load --1.2W/CH (typical) into a 8Ω Load Bridge-Tied Load (BTL), Single-Ended (SE) Shutdown Control Available Dual Inline Package 16 pin (DIP16)
