Stereo Headphone Power Amplifier Features High performance Class AB amplifier High signal-to-noise ratio Low distortion Low power consumption Large output voltage swing Excellent power supply ripple rejection 3.0V to 6.5V supply voltage range Surface-Mount package-SOP 8 Applications CD-ROM DVD-ROM CD-R/W MP3 Portable Stereo 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 16 Ω loads & 75mW into 32 Ω 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. Ordering Information ORDER NUMBER MARKING TEMP.
