Offset null pins op amp

Webb741 has three stages: input differential amplifier, voltage gain, and output buffer. Offset null pins allow you to trim the input differential amplifier legs to remove input offset … Webb8 dec. 2024 · In this circuit, the offset voltage added to the output is Vos (1+Rf/Ri) where Vos is the voltage at the non-inverting input of the op-amp. The full range of adjustment for Vos is ±15V × R2/ (R1+R2). With R1=470kΩ and R2 set to 100Ω with a 50kΩ, 32 tap, EPOT, the full range of adjustment is ±3.2mW and each step is ~2mV.
