Industry's first skin electrical reflex measurement reference design accelerates wearable device development

China, Beijing, May 20, 2015. Maxim Integrated Products, Inc. (NASDAQ: MXIM) introduced the MAXREFDES73# reference design to help wearable developers quickly evaluate skin electrical reflectance (GSR) measurement systems.

GSR (skin conductivity measurement) design faces significant challenges, and designers need to be familiar with a variety of discrete devices and calibration software before completing sensor design. The MAXREFDES73# is the industry's first GSR reference design that integrates a digital-to-analog converter (DAC) and an analog-to-digital converter (ADC), as well as a microcontroller with advanced power management features, firmware and an easy-to-use Android® app. Save time on the development and testing of wearable products and help users bring mobile medical/health products to market quickly. The MAXREFDES73# is available in a wristband package that includes temperature readings, Bluetooth® communication, and a rechargeable battery (a single battery lasts up to a week).

Main advantage

Speed ​​time to market: integrated DAC and ADC signal chain, low power microcontroller, and Bluetooth and Android app, firmware to speed development and test design process

High precision: 16-bit integrated analog front end (AFE)

Low power consumption: up to one week for a single battery
