FEATURES
GENERAL DESCRIPTION
To simplify the audio system design in the notebook application, G1420 supports the Bridge-Tied Load (BTL) mode for driving the speakers, Single-End (SE) mode for driving the headphone. G1420 can mute the output when Mute-In is activated. For the low current consumption applications, the SHDN mode is supported to disable G1420 when it is idle. The current consumption can be further reduced to below 5µA. G1420 also supports two input paths, that means two different gain loops can be set in the same PCB and choosing either one by setting HP/ LINE pin. It enhances the hardware designing flexibility.
