Design a Custom BoardAbout This Component
Precision current-sense amplifier with integrated shunt monitor for measuring DC and AC currents up to 1A. Provides differential voltage output proportional to current flow across external shunt resistor. Ideal for battery management systems, power supplies, and load monitoring applications requiring accurate current measurement.
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.
