I need to amplify the signal from a sensor into an ADC. I have very little analog experience or knowledge. Circuit supply voltage is +3.3 volts. Output impedance of transducer is 1K typical. Full output voltage span of sensor is 35mV typical. Nominal input impedance of ADC is 10K. I want to amplify the DC voltage from the sensor to the ADC as much as possible. Linearity, temp drift and offset is not too much of an issue. Can this be done with perhaps a mosfet and a couple resistors? Is there a small package (like a TO92 or 3 pin package) that will do the trick?
