Creation and Simulation of a 1kV High Common Mode Voltage Difference Amplifier circuit with TINA offline version or online with TINACloud

Achieving a high common mode voltage differential amplifier requires a very high attenuation resistor network. To minimize op amp input offset voltage and drift errors, an autozero type is used– OPA735.  An OPA335 can be used on a 5V supply. Common- mode rejection is critically dependent on the ratio matching of R3:R2 & R4:R1. These should be matched to extremely tight tolerances. Power dissipation in R3 & R4 are significant. Bypass capacitors are not shown.  (Circuit is created by Neil P. Albaugh  TI – Tucson)
