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.
A simple 3-wire up/down interface allows manual switching
or high speed digital control with clock rates up to 50 MHz.
