Design a Custom BoardAbout This Component
Hall effect current sensor IC for AC/DC current measurement up to ±12.5A with integrated low-resistance copper conductor path (1.2mΩ). Single-supply operation (3-5.5V), 100kHz bandwidth, and ratiometric analog output. Ideal for circuit protection, current monitoring, and motor control in low-voltage applications without external sense resistor.
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.
