Design a Custom BoardAbout This Component
Single-channel instrumentation amplifier IC in 8-SOIC package for precision differential signal conditioning. Provides high input impedance and CMRR for accurate measurement of low-level signals in data acquisition, sensor interface, and analog front-end applications. Ideal for converting differential inputs to single-ended outputs with selectable gain.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
