This is the user guide for ADN2850 digital rheostat evaluation board from Analog Devices. The evaluation board includes multiple test circuits and can be controlled by PC.
This document is the user guide for the EVAL-ADN2850SDZ evaluation board, designed to evaluate the ADN2850 dual-channel, 1024-position, nonvolatile memory digital resistor. The board supports various test circuits, including pseudo-logarithmic and pseudo-antilogarithmic DACs, a signal amplifier, and current monitoring, with inputs for AC/DC signals.
| Device Type | Dual-channel, 1024-position, nonvolatile memory digital resistor |
|---|---|
| Interface Speed | Up to 50 MHz |
| Operating Voltage (Single Supply) | 2.7 V to 5.5 V |
| Operating Voltage (Dual Supply) | ±2.25 V to ±2.75 V |
