Datasheet
Examples of circuit
○Voltage follower
Voltage gain is 0 dB.
VCC
This circuit controls output voltage (OUT) equal input
voltage (IN), and keeps OUT with stable because of
high input impedance and low output impedance.
OUT is shown next formula.
OUT=IN
OUT
IN
VEE
○Inverting amplifier
R2
VCC
For inverting amplifier, IN is amplified by voltage gain
decided R1 and R2, and phase reversed voltage is
output.
R1
IN
OUT
OUT is shown next formula.
OUT=-(R2/R1)・IN
Input impedance is R1.
R1//R2
VEE
○Non-inverting amplifier
For non-inverting amplifier, IN is amplified by voltage
gain decided R1 and R2, and phase is same with IN.
OUT is shown next formula.
OUT= (1+R2/R1)・IN
This circuit realizes high input impedance because
Input impedance is operational amplifier’s input
Impedance.
