G1426 General Description
The G1426 is a stereo audio power amplifier in 20pin TSSOP package. It can deliver 2W continuous RMS power into 4 load per channel in Bridge-Tied Load (BTL) mode at 5V supply voltage under 1% THD. To simplify the audio system design in the notebook application, The G1426 supports the Bridge-Tied Load (BTL) mode for driving the speakers. For the low current consumption applications, the SHDN mode is supported to disable the G1426 when it is idle. The current consumption can be further reduced to below 2A.

G1428 General Description
G1428 is a stereo audio power amplifier in 24pin TSSOP thermal pad package. It can drive 2.0W continuous RMS power into 4 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, G1428 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 G1428 when it is idle. The current consumption can be reduced to 160µA (typically).
Amplifier gain is internally configured and controlled by two terminals (GAIN0, GAIN1). BTL gain settings of 2, 6, 12, 24V/V are provided, while SE gain is always configured as 1V/V for headphone driving. G1428 also supports two input paths, that means two different amplitude AC signals can be applied and chosen by setting HP/ LINE pin. It enhances the hardware designing flexibility.
