Product details
Overview
AD5290YRMZ10 from Analog Devices is a 256-position, 10 kΩ digital potentiometer in MSOP-10 package, operating from +30 V single supply or ±15 V dual supply. 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 datasheet, AD5290YRMZ10 pinout, AD5290YRMZ10 application, or AD5290YRMZ10 equivalent, this page delivers verified electrical specs, terminal roles, automotive-grade temperature performance (−40°C to +125°C), and real-world design implications for high-voltage analog control circuits.
Technical Context
The AD5290YRMZ10 implements a 3-stage segmented RDAC architecture using iCMOS™ process, enabling ±15 V operation while maintaining low power (765 μW typical) and monotonic 256-step resolution. Its wiper resistance (50–100 Ω) and 35 ppm/°C end-to-end tempco are specified across −40°C to +125°C.
In potentiometer divider mode, it achieves 5 ppm/°C voltage divider tempco and ±0.3 LSB INL/DNL; in rheostat mode, it delivers ±0.7 LSB R-INL and ±0.3 LSB R-DNL at 10 kΩ. Terminal voltage range spans VSS to VDD with no polarity restriction between A, B, and W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resistance Value | 10 kΩ nominal, ±30% tolerance at +25°C - defines full-scale analog range in gain/offset circuits. |
| Supply Range | +4.5 V to +33 V single supply or ±4.5 V to ±16.5 V dual supply - supports industrial high-voltage rails. |
| Resolution | 256 positions (8-bit) - enables 0.39% step resolution for precision trimming and closed-loop control. |
| Tempco | 35 ppm/°C (resistor), 5 ppm/°C (voltage divider) - ensures stable ratio-based operation over automotive temperature range. |
| THD | 0.006% typical at 1 kHz - meets audio and precision signal-path requirements without distortion artifacts. |
| Interface | 3-wire SPI-compatible (CS, CLK, SDI, SDO) - allows daisy-chaining and microcontroller integration with <100 ns propagation delay. |
| Settling Time | 4 μs to ±1 LSB - enables fast reconfiguration in dynamic gain-control loops. |
Pinout & Package
AD5290YRMZ10 uses a compact 3 mm × 3 mm MSOP-10 package with exposed pad (θJA = 230°C/W), rated for −40°C to +125°C operation and compatible with automated PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Resistor Terminal A | High-side analog node; voltage range VSS to VDD; no polarity constraint vs. B or W. |
| B | Resistor Terminal B | Low-side analog node; voltage range VSS to VDD; forms resistive ladder with A and W. |
| VSS | Negative Supply | Connect to 0 V in single-supply mode; required for dual-supply biasing and ESD protection integrity. |
| GND | Digital Ground | Reference for CS, CLK, SDI logic; must be tied to system digital ground, separate from analog ground if needed. |
| CS | Chip Select Input | Active-low enable; rising edge latches serial data into wiper register; controls daisy-chain timing. |
| CLK | Serial Clock Input | Positive-edge triggered; max 4 MHz; determines update rate and noise immunity in noisy environments. |
| SDI | Serial Data Input | MSB-first 8-bit command; loads wiper position or configures mode; requires 30 ns setup time. |
| SDO | Serial Data Output | Open-drain N-Ch FET; shifts out prior frame's SDI for daisy-chain; needs external 2.2 kΩ pull-up. |
| VDD | Positive Supply | Primary power rail; supports up to +33 V; powers analog core and digital interface simultaneously. |
| W | Wiper Terminal | Variable tap point; resistance to A/B varies digitally; max continuous current ±5 mA (pulsed ±20 mA). |
Key Features
| Feature | Design Value |
|---|---|
| iCMOS™ Process Technology | Enables ±15 V analog operation with CMOS-level digital logic, reducing package size and power vs. legacy processes. |
| Midscale Preset | Power-on defaults to code 0x80 (midpoint), ensuring known startup resistance without host initialization. |
| Automotive Temperature Range | Guaranteed operation from −40°C to +125°C - qualified for under-hood and industrial control applications. |
| Low Leakage | 1 nA common-mode leakage at A/B/W - preserves accuracy in high-impedance sensor interfaces and filter nodes. |
| Glitch-Free Transition | Midscale transition avoids output glitches (Figure 16), critical for stable feedback in power supply loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5292YRMZ10 | Same 10 kΩ value and MSOP-10 package, but 1024-position (10-bit) resolution and higher 10 MHz clock support. | Higher resolution required for fine-grained gain calibration; not drop-in due to different register map and timing. | Select AD5292YRMZ10 when >256 steps or faster update rates are needed; verify firmware compatibility. |
| MAX5487ETA+T | 100 kΩ default, 256-tap, SPI interface, but only +5.5 V max supply and −40°C to +85°C rating. | Limited to low-voltage consumer applications; cannot replace AD5290YRMZ10 in ±15 V or automotive environments. | Choose MAX5487ETA+T only for cost-sensitive, non-automotive designs with ≤5.5 V rails and relaxed temp range. |
Compared with AD5290YRMZ10, AD5292YRMZ10 offers finer resolution and speed at the cost of firmware adaptation, while MAX5487ETA+T sacrifices voltage range and temperature capability for lower cost and smaller footprint in benign environments.

FAQ
What is the maximum operating voltage for AD5290YRMZ10?
The AD5290YRMZ10 supports absolute maximum ratings of VDD to GND = +35 V and VSS to GND = −16.5 V, with recommended operating range up to +33 V single supply or ±16.5 V dual supply. Exceeding these limits risks permanent damage per Absolute Maximum Ratings Table 5. The AD5290YRMZ10 must be powered within these boundaries to ensure reliable operation and longevity.
Does AD5290YRMZ10 support daisy-chaining multiple devices?
Yes, AD5290YRMZ10 supports daisy-chaining via its open-drain SDO pin, which shifts out the previous frame's SDI data. Each device requires an external 2.2 kΩ pull-up resistor on SDO, and clock period must be increased to accommodate capacitive loading between SDO and the next SDI. This enables synchronized updates across multiple AD5290YRMZ10 units using a single SPI bus.
What is the guaranteed temperature coefficient for AD5290YRMZ10 resistance?
The AD5290YRMZ10 guarantees a resistance temperature coefficient of 35 ppm/°C across −40°C to +125°C for the 10 kΩ version, as confirmed in Table 1 and General Description. This applies to end-to-end resistance (RAB); voltage divider mode achieves improved 5 ppm/°C tempco due to ratio-based operation, enhancing stability in gain-setting applications.
Can AD5290YRMZ10 operate from a single +5 V supply?
AD5290YRMZ10 is functional at +4.5 V, but key specifications including THD, bandwidth, and tempco are only guaranteed from +30 V single supply or ±15 V dual supply per Electrical Characteristics tables. At +5 V, performance degrades significantly - e.g., bandwidth drops and distortion increases - so AD5290YRMZ10 should not be used in +5 V systems where datasheet performance is required.
Is the wiper resistance of AD5290YRMZ10 constant across codes and temperature?
No - AD5290YRMZ10 wiper resistance (RW) ranges from 50 Ω to 100 Ω and doubles from +25°C to +125°C, though it remains flat across codes at fixed temperature and VDD. This variation must be accounted for in precision rheostat-mode designs, especially near zero- or full-scale positions where RW contributes significantly to total RWB or RWA. The AD5290YRMZ10 datasheet provides RW values in Tables 1 and 2.
