The AD5111/AD5113/AD5115 provide a nonvolatile solution 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. The AD5111/AD5113/AD5115 are available in a 2 mm × 2 mm LFCSP package. The parts are guaranteed to operate over the extended industrial temperature range of −0℃ to +125℃.

AD5111评估板
This user guide describes the evaluation board for evaluating the AD5111—a single-channel, 128-position, nonvolatile memory digital potentiometer.
The AD5111 supports single-supply 2.3 V to 5.5 V operation, making the device suited for battery-powered applications and many other applications, offering guaranteed low resistor tolerance errors of ±8% and high bandwidth while allowing up to ±6 mA current density in the A, B, and W pins.
A simple 3-wire up/down interface allows manual switching or high speed digital control with clock rates up to 50 MHz. The EVAL-AD5111SDZ can operate in single-supply mode and incorporates an internal power supply from the USB.
Complete specifications for the AD5111 part can be found in the AD5111 data sheet, which is available from Analog Devices, Inc., and should be consulted in conjunction with this user guide when using the evaluation board.
