Tag: low distortion amplifier

This discrete JFET input line stage can drive a 2k ohm load to 6V RMS in class A at less than 30 ppm distortion and at 3V RMS into 2k ohms, the distortion is around 7ppm at 1 kHz. The output stage runs at 20mA standing current. A jumper allows the user to select either…
