General Description
The G1401 is a stereo audio power amplifier housed
in a 8-pin SOP package capable of delivering 135mW
of continuous power per channel into 16Ω loads.
Amplifier gain is externally configured by means of two
resistors per input channel.
The G1401 is a dual channel, low voltage, low power,
performance OP amps that can be designed into a
wide range of headphone driving applications, at an
economical price.
