  • Offset Voltage adjustment for OP177

    Dear Sir/Madam,

    Our customer asked th following question to me.

    As for your OPAMP OP177GSZ,

    your datasheet shows the adjustable offset voltage adjustment range is +/-3mV typ by adding 20kohm POT on Rp.

    So if we need it +/-6mV, then what is the external…
