GENERAL DESCRIPTION
The
for 128-/64-/32-position adjustment applications, offering
guaranteed low resistor tolerance errors of ±8% and up to
±6 mA current density in the A, B, and W pins. The low resistor
tolerance, low nominal temperature coefficient and high
bandwidth simplify open-loop applications, as well as tolerance
matching applications.
The new low wiper resistance feature minimizes the wiper
resistance in the extremes of the resistor array to only 45 Ω,
typical.
The wiper settings are controllable through an I
digital interface that is also used to readback the wiper register
and EEPROM content. Resistor tolerance is stored within
EEPROM, providing an end-to-end tolerance accuracy of 0.1%.
