While both operational amplifiers and voltage comparators have been with us since before 1970, the similarities and differences tend to be vague. This discussion will help in understanding this ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

Most older and a few current IC op amps have a separate null or trim pin input to which a corrective voltage can be applied. Another solution is to add a resistor in the non-inverting input, which ...

In 2008, Kendall Castor-Perry began an extended investigation into the effect that bypass capacitor selection has on analog circuit performance. Five years on, we’re re-posting this classic series, ...

This is called electromagnetic induction close electromagnetic inductionThe production of a potential difference (voltage) when a conductor, such as a wire, is moved through a magnetic field or ...

According to ROHM, its ultra-compact TLR1901GXZ CMOS op amp is the industry’s lowest operating circuit current. The op amp is ...

ROHM Semiconductor today announced the development of the TLR1901GXZ, an ultra-compact CMOS operational amplifier (op amp) that achieves the industry’s lowest operating circuit current. Optimized for ...
