GENERAL DESCRIPTION
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.
A simple 3-wire up/down interface allows manual switching
or high speed digital control with clock rates up to 50 MHz.
LFCSP package. The parts are guaranteed to operate over the
extended industrial temperature range of 40°C to +125°C.
