STMicroelectronics has created a 100V capable precision current-sense amplifier with 120dB rejection of PWM signals. Called TSC240 and capable of bi-directional sensing, it will also work with its ...

High-side current-sense amplifiers (CSAs) are principally used for monitoring the current from a positive supply rail. However, applications like ISDN and telecom power supplies require CSAs that ...

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 ...

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 ...

Input bias current is a usually overlooked amplifier parameter that can have a significant effect on an amplifier circuit’s output accuracy. Sometimes the effect is small enough to be ignored, but ...
