Design a Custom BoardAbout This Component
Ultra-precise bidirectional current sense amplifier for high-voltage applications with ±5V to 110V common-mode range. Features 20V/V gain, 166dB DC-CMRR, ±10µV offset, and enhanced PWM rejection for switching frequencies to 125kHz. Ideal for motor drives, power tools, and drone speed control requiring accurate shunt 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.
