General Description
G1428 is a stereo audio power amplifier in 24pin
TSSOP thermal pad package. It can drive 2.0W con-
tinuous RMS power into 4惟 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 160碌A(chǔ) (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 de-
signing flexibility.
