Description

This the 'MOX' JFET DOA. At it's core is the highly respected NEC UP686 matched JFET pair.

The MOX Discrete OpAmp is a 'tried and true' simple discrete single-ended Class A gain stage. It was designed to be operated at low gain and feedback levels with high performance and stability. In the KAD version of this classic circuit the input pair is a NOS (New Old Stock) JFET NEC UP686. That matched FET pair drives a PNP bipolar gain transistor which is also a level-shifter. Both gain stages are driver by NPN bipolar current sources which are in turn regulated by an NPN bipolar voltage reference taking feedback from the first current source.

The distortion and noise imposed on a signal running through this circuit is very low, typically being under 0.05% at +/-15 to 18 volts. Signal bandwidth is flat from DC to beyond 100 KHz.

The MOX Discrete OpAmp is packaged in the Pro legacy 2520 pinned format and can be installed into legacy hardware.
