The AD5111 provides a nonvolatile solution for 128-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.
The AD5111 is available in a 2 mm × 2 mm LFCSP package. The parts are guaranteed to operate over the extended industrial temperature range of −40°C to +125°C.
