• Description: Digital Potentiometer ICs Evaluation Kit/Evaluation System for the MAX5477/MAX5478/MAX5479
• Manufacturer: Maxim Integrated

Specifications of MAX5478EVKIT

• Resistance: 50 kOhms
• Number Of Pots: Dual
• Taps Per Pot: 256
• Wiper Memory: Non Volatile
• Digital Interface: Serial (2-Wire, I2C)
• Operating Supply Voltage: 5 V
• Supply Current: 15 uA
• Supply Voltage - Max: 5.25 V
• Supply Voltage - Min: 2.7 V

The MAX5478 EV kit requires a 2.7V to 5.25V power sup-
ply connected across the VDD and GND pads for nor-
mal operation. The EV kit can also use the CMODUSB
command module’s 3.3V or 5V power source by
installing a shorting jumper across JU5 of the MAX5478
EV kit. Configure the command module’s VDD select
voltage to 3.3V or 5V (jumper J1) when using the com-
mand module to power the MAX5478 EV kit.

Note: Ensure that all the data sheet absolute maximum
specifications are not violated when operating the
MAX5478 EV kit.
The MAX5478 EV kit PC board can be used to evaluate
the MAX5477 or MAX5479 dual digital potentiometers.
Remove the MAX5478 IC (U1) and replace it with the
new IC. The MAX5477 and MAX5479 ICs are pin and
function compatible with the MAX5478 IC. Refer to the
MAX5477/MAX5478/MAX5479 data sheet for a complete
description of part-to-part differences.
