MAX5474 Evaluation Kit
Evluates:/MAX475
General Description
Features
♦ 2.7V to 5.25V Single-Supply Operation
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.
♦ Power-On Recall of Wiper Position from
Nonvolatile Memory
♦ On-Board USB Interface Circuit
♦ USB Powered
♦ USB-PC Connection (Cable Included)
♦ Stand-Alone Operation Using On-Board Switches
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.
♦ PCB Pads for User-Supplied Microcontroller
Interface Signals
♦ PCB Pads for Potentiometer Signals (L, W, H)
♦ Proven USB-Compatible PCB Layout
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).
♦ Evaluates the MAX5474/MAX5475 in 8-Pin SOT23
Package
♦ Windows 2000/XP/Vista (32-Bit)-Compatible
Software
♦ Fully Assembled and Tested
