Design a Custom BoardAbout This Component
Single-channel current sense amplifier in SOT-23-5 package with integrated shunt measurement capability. Provides high-side or low-side current monitoring with ±200mA range and adjustable gain via external resistors. Typical applications include battery management, motor control, and power supply monitoring.
Package: SOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
