Examples of circuit
○Voltage follower
Datasheet
VCC
OUT
Voltage gain is 0 dB.
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
IN
VEE
○Inverting amplifier
R1
IN
R2
VCC
R1//R2
VEE
○Non-inverting amplifier
OUT
For inverting amplifier, IN is amplified by voltage gain
decided R1 and R2, and phase reversed voltage is
output.
OUT is shown next formula.
OUT=-(R2/R1)・IN
Input impedance is R1.
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.
