In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...
Digitally-actuated potentiometers, or digipots, are commercially available from multiple suppliers but not analog-actuated potentiometers, or anapots. The following isolated anapot, or isopot, design ...
