Manufacturer Part Number
ds1806e-100t-r
Description
Ds1806 Digital Sextet Potentiometer
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
DS1806
Wiper placement for each potentiometer is such that position-63 corresponds to the H
terminal of the de-
X
vice while position-0 corresponds to the ground terminal. For example, to set a potentiometer’ s wiper
position to 15 (decimal), the binary value shifted into the wiper register should be 00001111. This will
th
place the wiper tap at the 15
step above the low-end terminal, L
.
X
All communication transactions should provide the total 48 bits of information when writing or reading
from the part. This is especially true for applications using all six potentiometers. If a complete set of 48
bits is not transmitted to the part, undesired wiper position settings may occur.
