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 ...

New operational amplifiers optimized for high-performance audio and ultrasound applications combine extremely low total harmonic distortion plus noise (THD+N), -130 dB, with large output voltages on ...

Texas Instruments (TI) announced the availability of an audio operational amplifier (op amp) that sets the latest standard in audio performance. The OPA1622 is the newest addition to the company’s ...

TDA2822 is a low power stereo Op Amplifier used in Walkman players and Hearing aids. It can give 250 mW output. TDA2822 is an ideal Op amp for low output applications. It is a good choice as a ...

ISSCC, the International Solid-state circuits conference, is the IEEE’s annual showcase for all that is best in on-chip circuit design from across the globe. Thousands of engineers will flock there ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can do that with an op amp ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...
