The AG001-01E GMR Analog Sensor Evaluation Kit is designed for experimentation and development. The kit contains an assortment of 14 NVE analog sensors plus several printed circuit boards and various permanent magnets. It includes the high-sensitivity AAH002 sensor. The kit contains only RoHS compliant parts.
The evaluation board includes three sensor over current-trace modules with three AAL024-10E TDFN current sensors.
The board measures 1.565" x 2.915" (40 mm by 74 mm), and includes three separable modules. The three modules are optimized to measure currents of 0-0.75A, 0-5A, and 0-50A.
A preassembled circuit board with a high-sensitivity AAH002-02E sensor and a differential amplifier circuit with a gain of 25. The board can be powered by a 2.7 to 12 V supply and provides a single-ended output with a typical sensitivity of 3.75 V/V/mT (375 mV/V/Oe).The circuit board is 12.5 x 7.8 mm, with Vcc, GND, and OUT plated-through holes for wires or a header.
