Analog Evaluation System
A versatile and easy-to-use tool!
This Analog Evaluation System gives system designers the ability to control
Microchip stand-alone analog devices, acquire data and then analyze the data
using stripcharts, histograms and Fast Fourier Transforms (FFTs). User-friendly
data analysis software is included with the device-specific Daughter Boards.
The evaluation system consists of two parts: a Driver Board, which performs the
data analysis and connects to a PC for subsequent analysis and display; and a
Daughter Board, which plugs into the Driver Board and contains the device to be
evaluated. Device-specific software is included.
In addition to the ability of the Driver Board to work with device-specific
Daughter Boards, users can create their own daughter boards based on their
own design requirements. Also, there is a prototype area on the Driver Board for
user-designed circuits that could be used in place of the Daughter Boards.
The Daughter Boards include the device under evaluation and associated
interface circuitry. It may also include components for signal stimulus and
connectors for an external signal. On the DV3204A Daughter Board, for
example, choices include selection of the ADC input channel, the ADC reference
voltage source and the routing of the signal through buffers and/or filters.
Daughter Boards are currently available for the following products:
MCP32001/01, MCP3004/08, MCP3201/02 and MCP3204/08.
Additions to this Analog Evaluation System will be released to coincide with new
product introductions.
