MAX9924UEVKIT

Evaluation Kit for the MAX9924U and MAX9925


Please check latest availability status for a specific part variant.

Description

The MAX9924U evaluation kit (EV kit) is a fully assembled and tested PCB that contains a differential variable reluctance (VR) sensor interface circuit using a MAX9924U IC in a 10-pin µMAX® package. The single-channel interface circuit also features a differential amplifier for evaluating differential or single-ended VR sensor (magnetic pickup sensor) signal, and provides a fixed gain of 1V/V. Input power to the EV kit circuit can be supplied by a 4.5V to 5.5V DC source. The MAX9924U IC temperature range is -40°C to +125°C.

The MAX9924U EV kit circuit can be configured to demonstrate the MAX9924U IC's operation with internal adaptive peak threshold and zero-crossing detection modes. It can also interface to a microcontroller PWM signal for evaluating external thresholds. Additionally, a configurable on-board triangle-wave generator using a MAX9000 IC provides a 5Hz, 55Hz, 2.5kHz, or 24kHz triangle-wave signal if no external VR signal is available for evaluation.
