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 ...

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...

There's been an explosion of portable devices with the added capability of running their audio through external speakers—MP3 players, cell phones with MP3 functions or a speakerphone, and portable CD ...

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.

ADL5580 is a SiGe dc to 10.0GHz differential-in differential-out gain block from Analog Devices, which has a digital bus for signal path tweaking. “The amplifier offers a referred-to-input noise ...

Analog Devices has introduced what it claims to be the industry's first 5GHz differential amplifier able to drive ADC signals from DC to 1GHz at half the power of similar products. The ADA4960-1 ...
