Global Mixed-mode Technology Inc. Stereo Headphone Power Amplifier G1301 Features General Description Class AB amplifier High performance High signal-to-noise ratio Low distortion Low power consumption Large output voltage swing Excellent power supply ripple rejection 4.0V to 6.0V supply voltage range Surface-Mount package-SOP 8 The G1301 is a stereo audio power amplifier housed in a 8-pin SOP package capable of delivering 60mW of continuous power per channel into 32Ω loads. Amplifier gain is externally configured by means of two resistors per input channel. The G1301 is a dual channel, low voltage, low power, high performance OP amps that can be designed into a wide range of headphone driving applications, at an economical price.
