Design a Custom BoardAbout This Component
Quad-channel current sense amplifier with integrated shunt measurement supporting up to ±80mV input range. Features 20-TSSOP surface mount package enabling compact multi-channel current monitoring in power management, battery charging, and load detection applications.
Package: TSSOP-20 (4.4×6.5mm) · 20 pins
Why does this need a breakout?
Hand-soldering 0.65mm pitch leads is tedious and error-prone; a breakout board with standard 0.1" headers lets you prototype I/O expanders and logic gates on breadboards without a reflow oven. The compact SSOP package also becomes DIP-friendly, eliminating jumper spaghetti and reducing assembly mistakes during development cycles.
