MAX9924U Evaluation Kit

Evluates:4U/MAX925

General Description

Features

The MAX9924U evaluation kit (EV kit) is a fully assem-

bled and tested PCB that contains a differential variable

reluctance (VR) sensor interface circuit using a

♦ Demonstrates MAX9924U MODE A1, A2, B, and C

Operation

♦ Evaluates Differential and Single-Ended Sensors

MAX9924U IC in a 10-pin µMAX package. The single-

(VR or Magnetic Pickup)

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.

♦ Demonstrates Zero-Crossing and Adaptive

Threshold Mechanism

♦ Includes Lowpass Sensor Input Filter

♦ On-Board 5Hz/24kHz Triangle-Wave Generator

♦ Evaluates MAX9925 (IC Replacement Required)

♦ Lead(Pb)-Free and RoHS Compliant

♦ Fully Assembled and Tested

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.
