The single op-amp differential amplifier shown in Figure 1 is often used as an audio balanced line receiver. Obtaining high common-mode rejection is a critical requirement that requires four ...

Amplifier circuit offsets are always an important topic for any amplifier design. Most voltage amplifier circuit offsets are a result of the amplifier’s input voltage offset, input bias current and ...

Members can download this article in PDF format. Use of differential signaling in analog front ends is increasing across a range of applications, from audio processing to factory automation.

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...
