General Description
The MAX5408–MAX5411 dual, logarithmic taper digital
potentiometers, with 32-tap points each, replace
mechanical potentiometers in audio applications requir-
ing digitally controlled resistors. The MAX5408/
MAX5410 are dual potentiometers with one wiper per
potentiometer. The MAX5409/MAX5411 are dual poten-
tiometers with two wipers per potentiometer (see
Functional Diagram). An SPI-compatible serial inter-
face controls the wiper positions. The MAX5408–
MAX5411 have a factory-set resistance of 10k per
potentiometer. A zero-crossing detect feature mini-
mizes the audible noise generated by wiper transitions.
The MAX5408–MAX5411 have nominal temperature
coefficients of 35ppm/°C end-to-end and 5ppm/°C
ratiometric. The MAX5408–MAX5411 are available in
16-pin QSOP and 16-pin thin QFN packages and are
specified over the extended temperature range (-40°C
to +85°C).
