Dual Polarity Analog Output Op-Amps
When you have to buffer and invert the polarity of mV input levels. This is the circuit you can use, as OP07 has uV offset. R9 and R10 can be 100K 1% MFR or better. Use a symmetrical dual supply.
OP07: Ultralow Offset Voltage Operational Amplifier
Both the output are identical but opposite polarity. Only low offset opamp can make this possible. We also have to consider temperature stability, environment, emi and thermoelectric emf when working with micro-volts.
Ensure the opamp circuit including the 1% resistors are away from power electronic circuits like output drivers and power supplies. A hot Mosfet close to a 1% resistor will need Sherlock Homes to fix your design, which is flawless. The layout was kaput.
