Op-amp gain stage for a sensor

Easy · Whiteboard

A sensor outputs 0–200 mV. Amplify it to use most of a 0–3.3 V ADC range, with the op-amp on a single 3.3 V supply. Draw the circuit, pick resistors, and name what to check in the op-amp datasheet. The op-amp has a 1 MHz gain-bandwidth product: what bandwidth do you get?
