The SK7203 is a discrete linear integrated amplifier circuit from the RCA Corporation. It was originally designed for audio applications but can be used for other linear applications. It is a monolithic device featuring a differential input, direct coupling of the inputs, and an emitter follower output. Its operating voltage range is from 4 volts to 40 volts, providing plenty of power for most linear applications. The differential inputs provide excellent noise immunity and the direct coupling allows wide frequency response with low distortion. It also features a large output dynamic range and low DC offset. This amplifier is ideal for use in audio circuits or other high frequency applications requiring a low noise amplifier.
