APPLICATION NOTE 4288
How to Calculate the Wiper Voltage of a Digital Potentiometer
By: Bill Laumeister
Abstract: The MAX5481/MAX5483 data sheet provides a complicated formula for calculating wiper voltage in
an effort to be very precise. This application note explains the issues involved in this calculation and breaks
the process into smaller steps. It also discusses the proper method for determining the least-significant bit
(LSB).
