GENERAL DESCRIPTION
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 −40°C to +125°C.

1 Typical values represent average readings at 25°C, VDD = 5 V, VSS = 0 V, and VLOGIC = 5 V.
2 R-INL is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper positions. R-DNL measures the relative step
change from ideal between successive tap positions. The maximum wiper current is limited to 0.8 × VDD/RAB.
3 Guaranteed by design and characterization; not subject to production test.
4 INL and DNL are measured at VWB with the RDAC configured as a potentiometer divider similar to a voltage output DAC. VA = VDD and VB = 0 V. DNL specification limits
of ±1 LSB maximum are guaranteed monotonic operating conditions.
5 Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on current direction with respect to each other.
6 CA is measured with VW = VA = 2.5 V, CB is measured with VW = VB = 2.5 V, and CW is measured with VA = VB = 2.5 V.
7 Different from operating current; supply current for NVM program lasts approximately 30 ms.
8 Different from operating current; supply current for NVM read lasts approximately 20 μs.
9 PDISS is calculated from (IDD × VDD).
10 All dynamic characteristics use VDD = 5.5 V and VLOGIC = 5 V.
11 Endurance is qualified at 100,000 cycles per JEDEC Standard 22, Method A117 and measured at 150°C.
12 Retention lifetime equivalent at junction temperature (TJ) is 125°C per JEDEC Standard 22, Method A117. Retention lifetime based on an activation energy of 1 eV
derates with junction temperature in the Flash/EE memory.
