3.7 Two Operational Amplifier Instrumentation Amplifier

Figure 3–6 shows area 200 equipped with a dual operational amplifier configured as a two-operational-amplifier instrumentation amplifier using a voltage reference and single power supply.

Basic setup is done by choice of input and feedback resistors. The transfer function for the circuit as shown is:

Where:￿

R212 = R206 and R221 = R203

VOUT +VIN ￿1 )2R212R220 )R212R221￿)VREF2

To cancel the effects of input bias current, set R217 = R212 R220 and set R202 = R206 R203, or use a 0-jumper for R217 and R202 if the operational amplifier is a low input bias operational amplifier.

The TLV431 adjustable precision shunt regulator, configured as shown, provides a low impedance reference for the circuit at about 1/2 V2+ in a 3 V system. Another option is to adjust resistors R211 and R213 for the desired VREF2 voltage. The formula for calculating VREF2 is:
