Discrete operational amplifiers for high voltage and current capability
better noise, higher voltage, higher currents


Discrete opamps have some features that the standard chip opamps can not offer, like high voltage capability, high output current or very low noise.
We offer the solid state discrete opamps with a choice of input transistors: JFET for low noise and high input impedance, bipolar for low noise, MOSFET for high input impedance.
The OPT429 tube opamp can be used in high radiation environments. Tubes also have unique low-noise characteristics.
