-Calculation-
1. Input Offset Voltage (Vio)
VIO = |VF1|
[V]
1+RF/RS
2. Input Offset Current (Iio)
|VF2-VF1|
IIO = RI ×(1+RF/RS)
[A]
3. Input Bias Current (Ib)
|VF4-VF3|
IB = 2 × RI ×(1+RF/RS) [A]
4. Large Signal Voltage Gain (Av)
AV = 20Log 10 × (1+RF/RS) [dB]
|VF5-VF6|
5. Common-mode Rejection Ration (CMRR)
6. Power supply rejection ratio (PSRR)
CMRR = 20Log 3.5 × (1+RF/RS) [dB]
|VF8-VF7|
PSRR = 20Log 25 × (1+ RF/RS) [dB]
