An op amp-based amplifier design overcomes errors associated with resistive current sensing, particularly those resulting from high commonmode voltages. Many current-sensing ICs are available for ...

This application note discusses the REF pin functionality in the indirect current-feedback architecture for instrumentation amplifiers. This article compares the importance of a REF buffer in a ...

Unlike traditional op amps, the high-side current-sense amplifier does not include an internal electrostatic discharge (ESD) protection diode from each Consider a typical battery-operated device in ...

It is often desirable to perform current sensing on the high side of a load. However, engineers must overcome design hurdles to successfully realize such an implementation. Now, with the availability ...

The low operating current of STMicroelectronics’ TSU111 nano-power op amp is on par with the leakage current of some low-cost capacitors, and would take over 25 years to discharge a 220mAh CR2032 cell ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...
