Explanation

Input Offset Voltage Drift

Input Offset Voltage Drift = ΔVIO / Δt

Δt : Amount of Temperature change.

ΔVIO : Amount of Input Offset Voltage.

Common Mode Input Voltage range A range of input voltage at which the operational amplifier can function.

Common Mode Rejection Ratio

Supply Voltage Rejection Ratio

Common Mode Input Impedance

Voltage Gain

CMR = 20log | ( ΔVIN / ΔVIO )|

ΔVIN : Amount of Input Voltage.

ΔVIO : Amount of Input Offset Voltage.

SVR = 20log |( ΔVS / ΔVIO )|

ΔVS : Amount of supply Voltage.

ΔVIO : Amount of Input Offset Voltage.

RINCM = ΔVIN / ΔIB

ΔVIN : Amount of Input Voltage.

ΔIB : Amount of Input bias current.

AV = 20log |( ΔVIN / ΔVO )|

ΔVO : Amount of output Voltage.

ΔVIN : Amount of Input Voltage.
