Overview
AD5290YRMZ10-R7 from Analog Devices is a 256-position, 10 kΩ digital potentiometer in MSOP-10 package, supporting ±15 V dual-supply or +30 V single-supply operation. It functions as a programmable resistor or voltage divider with 35 ppm/°C resistance tempco, 0.006% THD, and SPI-compatible 3-wire interface-used in high-voltage DACs and programmable power supplies.
For engineers reviewing the AD5290YRMZ10-R7 datasheet, AD5290YRMZ10-R7 pinout, AD5290YRMZ10-R7 application, or AD5290YRMZ10-R7 equivalent, key selection criteria include its ±15 V analog terminal rating, midscale preset capability, automotive-grade −40°C to +125°C operation, and guaranteed monotonicity in both rheostat and potentiometer modes.
Technical Context
The AD5290YRMZ10-R7 implements a patented 3-stage RDAC segmentation architecture enabling precise 8-bit wiper positioning across 256 taps. Its iCMOS™ process supports high-voltage operation while maintaining low power dissipation (765 μW typical) and low leakage (1 nA common-mode).
It features a daisy-chain-capable open-drain SDO output, positive-edge-triggered CLK, and active-low CS for synchronous serial programming. The device guarantees monotonic behavior with ±0.3 LSB DNL (typ) and ±0.7 LSB INL (typ) in potentiometer mode, and operates with 4 MHz max clock frequency and 4 μs wiper settling time.

FAQ
What is the maximum analog terminal voltage rating for AD5290YRMZ10-R7?
The AD5290YRMZ10-R7 supports analog terminal voltages from VSS to VDD. With ±15 V dual supply, Terminals A, B, and W tolerate −15 V to +15 V; with +30 V single supply, they tolerate 0 V to +30 V. Absolute maximum ratings specify VA/VB/VW to GND as VSS to VDD - exceeding this risks ESD diode conduction and potential damage. Always power VDD/VSS before applying analog signals.
Does AD5290YRMZ10-R7 support daisy-chaining, and how is it implemented?
Yes, AD5290YRMZ10-R7 supports daisy-chaining via its open-drain SDO pin, which shifts out the previous frame's SDI data. To chain multiple devices, connect one AD5290YRMZ10-R7's SDO (with external pull-up) to the next unit's SDI. All CS lines are tied together, and the master controller clocks 8 × N bits before raising CS. Propagation delay increases with chain length due to RC loading.
What is the significance of the midscale preset feature in AD5290YRMZ10-R7?
The midscale preset in AD5290YRMZ10-R7 automatically initializes the wiper to code 0x80 (128/256) on power-up, regardless of prior state or digital interface activity. This provides a known, repeatable startup condition - critical for safety-critical systems like programmable power supplies where undefined output voltage could damage downstream circuitry.
How does the 35 ppm/°C resistance temperature coefficient affect AD5290YRMZ10-R7 performance in rheostat mode?
In rheostat mode, the 35 ppm/°C resistance temperature coefficient means the end-to-end resistance RAB drifts predictably with temperature - e.g., a 10 kΩ part varies by ±0.42 kΩ over −40°C to +125°C. This impacts absolute resistance accuracy but not relative step matching, as DNL remains bounded. For ratio-critical uses, potentiometer mode (5 ppm/°C divider tempco) is preferred.
Can AD5290YRMZ10-R7 operate from a single +5 V supply?
No, AD5290YRMZ10-R7 requires minimum ±4.5 V dual supply or +4.5 V single supply, but its specified performance (e.g., THD, bandwidth, tempco) is only guaranteed at ±15 V or +30 V. At +5 V, functionality may persist, but parameters like 0.006% THD and 470 kHz bandwidth are not assured - Analog Devices explicitly states performance is not guaranteed below ±15 V operation.
