• Test & Measurement Equipment

Working Principle:

The OP481GSZ-REEL7 is based on a patented ultra-low noise input design that utilizes a special input section and very low-noise resistors. This amplifier reduces noise and distortion, resulting in remarkably low noise. The amplifier also has a high common-mode rejection ratio and a wide bandwidth, making it suitable for various applications.

The OP481GSZ-REEL7 is an instrumentation amplifier which is designed to provide a gain while rejecting any noise, or errors, arising from common-mode signals. It features a differential input stage, followed by a differential amplifier gain stage, and an output stage that can provide either single-ended or differential output. Common-mode rejection is achieved by amplifying the difference of the two inputs while suppressing any common-mode signals. The gain of the amplifier is set by two external resistors and typically ranges from 1 to 1000.

The OP481GSZ-REEL7 is designed to operate from a single 3-14V supply, and is protected from short circuits, overloads, and temperature variations, making it a highly reliable instrumentation amplifier. It is packaged in a miniature SOIC which allows the device to be used in space-constrained applications.
