General Description
The G1402 is an output rail-to-rail stereo audio power
amplifier housed in a 8-pin SOP package capable of
delivering 125mW of continuous power into 16loads
& 75mW into 32loads with the THD <0.1% per
channel.
The gain setting of the amplifiers can simply achieve
by setting two external resistors RI (input resistor) & RF
(feedback resistor) promptly.
The G1402 is a dual channel, low voltage, low power,
and high performance amplifiers. The quiescent
current is 3mA @ 5V typically. With excellent AC
performance (small THD), it can be designed into a
wide range of headphone driving applications.
