Analog Devices Inc./Maxim Integrated MAX44000EVKIT#

Overview

MAX44000EVKIT# from Maxim Integrated is an evaluation kit for the MAX44000 ambient and infrared proximity sensor IC, enabling rapid prototyping of touch-screen interface, presence detection, and adaptive display brightness control in portable electronics. It supports full functional validation of the sensor's 0.03–65,535 lux ambient light sensing, 850nm IR proximity detection, I²C register access, programmable interrupt behavior, and external IR LED drive (10–110mA).

For engineers reviewing the MAX44000EVKIT# datasheet, MAX44000EVKIT# pinout, MAX44000EVKIT# application, or MAX44000EVKIT# equivalent, this kit provides hardware-ready access to the MAX44000's ALS/PRX dual-sensing architecture, integrated ambient cancellation, single-pulse IR timing, and low-power operation modes - critical for smartphone, industrial sensor, and smart accessory development.

Technical Context

The MAX44000EVKIT# implements the MAX44000 sensor in a fully assembled, tested PCB layout with onboard voltage regulation (1.7V–3.6V), I²C pull-up resistors, configurable jumpers for INT polarity and mode selection, and test points for VDD, GND, SDA, SCL, DRV, and INT. It includes a calibrated external 850nm IR LED and optical path optimized for proximity reflectance measurement.

Kit firmware and GUI software (provided by Maxim) enable real-time register read/write, ALS/PRX data streaming, threshold configuration, gain tuning (green/IR channel), integration time selection (1.56–100ms), and persistent interrupt setup - all mapped directly to the MAX44000's documented register map (0x00–0x16) and electrical specifications.

FAQ

What is the primary function of the MAX44000EVKIT#?

The MAX44000EVKIT# is an evaluation kit for the MAX44000 ambient light and infrared proximity sensor IC. It provides a ready-to-use hardware platform with onboard power regulation, I²C interface, calibrated 850nm IR LED, and test points to validate the MAX44000's full feature set - including 0.03–65,535 lux ALS measurement, proximity detection with ambient cancellation, programmable interrupt logic, and 10–110mA IR LED drive capability.

Does the MAX44000EVKIT# include software tools?

Yes, the MAX44000EVKIT# ships with Maxim's official GUI software and firmware that support real-time register access, live ALS/PRX data streaming, threshold configuration, gain trimming (green/IR channels), integration time selection (1.56–100ms), and persistent interrupt setup - all aligned with the MAX44000's documented register map (0x00–0x16) and electrical behavior.

Can the MAX44000EVKIT# operate with both 3.3V and 5V host systems?

Yes, the MAX44000EVKIT# accepts either 3.3V or 5V DC input. Its onboard LDO generates the precise 1.7V–3.6V supply required by the MAX44000 IC, ensuring correct operation across both host voltage domains while maintaining compatibility with standard microcontroller I²C levels.

How does the MAX44000EVKIT# validate sunlight rejection performance?

The MAX44000EVKIT# enables verification of the MAX44000's built-in sunlight rejection through controlled testing: it supports measurement of proximity count stability (0 counts) under 0–100k lux ambient illumination without reflector, and quantifies <35% drop in proximity counts under high-lux conditions with black-glass reflector - confirming the IC's DC ambient cancellation and single-pulse IR synchronization as specified in its electrical characteristics.

Is the MAX44000EVKIT# RoHS-compliant and lead-free?

Yes, the MAX44000EVKIT# uses RoHS-compliant, lead-free components throughout, including the MAX44000GDT+ IC in its UTDFN-Opto package with exposed pad (EP), which is explicitly marked as lead(Pb)-free/RoHS-compliant per Maxim's ordering information and packaging documentation.
