Stereo Headphone Power Amplifier
Features
G1402
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 16Ω loads & 75mW into 32Ω loads 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.
High performance Class AB amplifier High signal-to-noise ratio Low distortion Low power consumption Large output voltage swing Excellent power supply ripple rejection 3.
