● EXPLANATION OF MEASUREMENT CONDITION
PARAMETER
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.
