Two-Op-Amp Instrumentation Amplifier

EC5912 can also be used to make a high input impedance two-op-amp instrumentation

amplifier as shown in Figure 5.

Where R1=R3 and R2=R4. If all resistors are equal,then Vo=2(V2-V1)

Single-Supply Inverting Amplifier

The inverting amplifier is shown in Figure 6. The capacitor C1 is used to block the DC

signal going into the AC signal source VIN. The value of R1 and C1 set the cut-off frequency to

fC=1/(2πR1C1). The DC gain is defined by VOUT=-(R2/R1)VIN

shown in Figure 8. The transfer function from VIN to VOUT is given by

Where the DC gain is defined by ALP=1+R3/R4, and the corner frequency is given by
