Circuit adds programmability to sensor amplifier:
Design Ideas / The pressure-sensor amplifier circuit of Figure 1 offers a number of advantages over the traditional approach using the classic three-op-amp instrumentation amplifier. The circuit can operate from a single supply and uses only two op amps and 1% resistors. If the reference voltage, VREF, is 0V, the transducer gain for the circuit isTo ensure equal gain for the two ground-referenced volt... . |
