EE 213: Linear Circuit Analysis Final Project Strain Gauge Amplifier A Force sensing strain gauge is rate at 2225 N. It is supplied by 11 V source and provides 3mV/V at the rated force. This means that the output of the staring gauge will be 33 mV if the force was 2225 N and -33 mV if the force was -2225N. Design an operation amplifier circuit to convert this voltage range from -33-33 mV to 0-3.3V. One terminal of the...
