The DEM-ADS1216 is a high-resolution analog-to-digital converter from TI. This evaluation board is used to evaluate the performance of the ADS1216. It supports 24-bit no missing code performance and has 8 input channels that can be configured as up to 8 differential channels. The multiplexer is followed by a programmable gain amplifier with selectable gains of up to 128. Hardware options include user defined clock frequency, internal or external reference, and input biasing. All of the ADS1216's features and functionality can be exercised using the pull-down menus available from the DEM-ADS1216 software.
The DEM-ADS1216 is an evaluation fixture designed for the ADS1216 high-resolution analog-to-digital converter. It features separate analog and digital power supplies, PC printer port control, and Windows 95/98 software for performance testing. The board includes a 2-layer PC design with surface-mount components and a divided ground plane to minimize parasitic effects.
| Resolution Performance | 24-bits no missing codes |
|---|---|
