  • Operational Amplifier Basics, Types and Uses Article MPS

    An operational amplifier (op amp) is an analog circuit block that takes a differential voltage input and produces a single-ended voltage output. Op amps usually have three terminals two high-impedance inputs and a low-impedance output port. The inverting input is denoted with a minus (-) sign, and the non-inverting input uses a positive ( ) sign.

  • How to Reduce Voltage with Resistors

    Let's do one more example. Say if you have the same circuit above with 5V but only want 1V. If we use a 10KΩ as our R1 resistor, plugging in the values, we get R2= (V)(R1)/(VINV)= (1V)(10KΩ)/(5V1V)= 2.5KΩ. So we can use a 2.5KΩ resistor as our R2 resistor with the R1 resistor being 10KΩ.. So it's easy to see now how any voltage can be obtained with a resistor voltage divider circuit.
