LTC6081 Single Supply Strain Gauge Amplifier

Aug 6th 2007
A dual CMOS amplifier with low supply voltage operation and rail to rail input and output performance makes single supply operation easy. This circuit provides a gain of 1001 to the small differential input signal from a low voltage strain gauge bridge transducer. High input impedance allows for high valued input resistors to ...

LT1002 Strain Gauge Signal Conditioner with Bridge Excitation

Jan 1st 1998
A buffered 7V reference provides a 5V excitation voltage to a balanced strain gauge resistor bridge. To provide a 0V output when the bridge is perfectly balanced, a second amplifier biases the bottom of the bridge to a negative compliment of the 5V excitation voltage. Using a dual matched amplifier package such as the LT1002 ...

LT1001 Strain Gauge Signal Conditioner with Bridge Excitation

Nov 1st 1983
A buffered 7V reference provides a 5V excitation voltage to a balanced strain gauge resistor bridge. To provide a 0V output when the bridge is perfectly balanced, a second amplifier biases the bottom of the bridge to a negative compliment of the 5V excitation voltage. Circuit gain is set such that a 1% bridge resistance imbalance ...
