General Description
The G1432 is a stereo audio power amplifier in 24pin TSSOP thermal pad package or 24pin QFN 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. The G1432 can mute the output when Mute is activated. For the low current consumption applications, the SHDN mode is supported to disable the G1432 when it is idle. The current consumption can be further reduced to below 5µA. The G1432 also supports two input paths, that means two different gain loops can be set in the same PCB and choosing either one by setting IN1 /IN2 pin. It enhances the hardware designing flexibility. The G1432 also supports an extra function -- the maximum output power clamping function to protect the speakers from burned-out.
