The EVAL-AD7716EB is an evaluation board for the AD7716, a 4-channel, 22-bit A/D converter. This high-resolution ADC is ideally suited for biomedical data acquisition systems such as ECG and EEG as well as general data acquisition applications.
The document provides an introduction to the EVAL-AD7716EB evaluation board for the AD7716, a 4-channel, 22-bit A/D converter. It details the hardware features, including input buffers, voltage reference, crystal oscillator, and interface circuitry designed for connection to a PC printer port.
The software requires a PC with an 80286 or higher microprocessor, at least 2Mb of RAM, and Microsoft Windows 3.0 or later.
When using a Compaq laptop, the user must select PRN as the printer port.
The digital filter can be programmed for three cut-off frequencies: 36.5Hz, 73Hz, and 146Hz.
