EV-HT-200CDAQ1
High Temperature Data Acquisition Reference Design Platform
The EV-HT-200CDAQ1 is a complete system reference platform enabling precision data acquisition and control in extreme temperatures up to
200°C. Based upon the AD7981 analog-to-digital SAR converter, this reference design demonstrates a full featured system with two high
speed simultaneously sampled channels along with 8 additional multiplexed channels suitable for covering the acquisition requirements for many
high temperature, harsh environment applications such as downhole oil and gas instrumentation. The data acquisition front end is connected to
the VORAGO Technologies VA10800 ARM® Cortex®-M0 based microcontroller via multiple SPI ports. Once acquired, the data can be processed
locally or transmitted via a UART or optional RS485 communications interface. In addition to the hardware, open source firmware uses
FreeRTOS with optimized drivers and a data acquisition protocol with multiple modes of operation. Open source host software allows the users to
connect to the board via UART to control acquisition modes, view data, log data and perform signal analysis. This platform is suitable as
reference design, for rapid prototyping and lab testing of high temperature instrumentation systems.
This reference design is a collaboration between ADI Alliance members VORAGO Technologies and Petromar Technologies and is the latest
addition to the growing ecosystem of products and solutions for high temperature applications from ADI. For more info on high temperature
