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 ...

While choosing an op-amp buffer, some sources of negative supply were considered, because the buffer op-amp had to provide true zero voltage on its output. In reality, a typical rail-to-rail output op ...

Most Hackaday readers will no doubt at some point used a solderless breadboard for prototyping. They do the job, but sometimes their layout can be inflexible and keeping track of signals can be a pain ...

As part of our Op-Amp Challenge we’re seeing a wide diversity of entries showcasing the seemingly endless capabilities of these extremely versatile parts. Another one comes from [Joseph Thomas], who ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

Switzerland-based STMicroelectronics (ST) has announced on March 9 its TSU111H 5V automotive operational amplifier with micro-power current consumption and 150°C operating-temperature capability.

Abstract: In this paper an improved version of the design procedure of two-stage CMOS operational amplifier employing a Miller capacitor and a current buffer is presented. Unlike the op amp obtained ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original. I was designing ...

In the old green board (piezo-preamp-tickler_V3-single-supply-OPA1612), pin 3 of the BAT54S is not connected to anything and pin 2 of the BAT54S is connected to two resistors R1, R2 and it is also ...
