The AD5247 digital potentiometer evaluation board user guide introduces the features and functions of the evaluation board, including the onboard components, test circuits, input signals, etc.
This document is the user guide (UG-397) for the EVAL-AD5247DBZ evaluation board, designed to evaluate the AD5247 single-channel, 128-position digital potentiometer. The board operates in conjunction with the low voltage digiPOT motherboard (EVAL-MB-LV-SDZ) and supports single-supply operation from 2.7 V to 5.5 V, making it suitable for battery-powered applications. It features various test circuits for DAC operation, AC signal attenuation, and signal amplification, controlled via a PC using the included software and a system demonstration platform (SDP-B or SDP-S).
The guide details the hardware specifications, including power supply connections and link options for configuring the board. It provides step-by-step instructions for installing and running the control software on Windows XP, Vista, and 7. Additionally, it includes schematics, component placement drawings, and a bill of materials for the motherboard and daughter board.
| Operating Voltage Range | 2.7 V to 5.5 V |
