Opamp systematic offset
Did you know?
WebOperational amplifiers, or op amps, are two-port integrated circuits (ICs) that apply precise gain on the external input signal and provide an amplified output as: input × closed-loop gain. Precision op amps behave close to ideal when operated at low to moderate frequencies and moderate DC gains. WebIn 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.
