General Description
G1427 is a stereo audio power amplifier in 24pin
TSSOP thermal pad package. It can drive 2.0W con-
tinuous RMS power into 4
Ω 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, G1427 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 G1427 when it is idle. The current
consumption can be reduced to 160A (typically).
Amplifier gain is internally configured and controlled by
two terminals (GAIN0, GAIN1). BTL gain settings of
6dB, 10dB, 15.6dB, 21.6dB are provided, while SE
gain is always configured as 4.1dB (inverting) for
headphone driving. G1427 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.
