MAX5474 Evaluation Kit
General Description
The MAX5474 evaluation kit (EV kit) is an assembled
and tested printed-circuit board (PCB) that evaluates
the MAX5474 IC. The MAX5474 is a 32-tap, 50kΩ non-
volatile, linear-taper digital potentiometer. Windows^®
2000/XP/Vista-compatible software is available to pro-
vide a convenient user interface for exercising the
MAX5474 features.
The MAX5474 EV kit provides three options to control
the MAX5474 wiper position using logic-input signals.
The MAX5474 logic-input signals can be controlled by
an on-board USB interface circuit, PCB interfacing
pads, or switches on the EV kit circuit for stand-alone
operation.
The EV kit can operate from a 3.3V source generated
from the USB interface circuit or from a 2.7V to 5.25V
external DC power supply. The EV kit can also evaluate
the MAX5475 (100kΩ) after IC replacement (U1).
