Product details
Overview
AD5290YRMZ100 from Analog Devices is a 256-position, 100 kΩ digital potentiometer in MSOP-10 package, operating from +30 V single supply or ±15 V dual supply. It delivers 35 ppm/°C resistance temperature coefficient, 0.002% THD, and ±0.5 LSB differential nonlinearity in potentiometer mode - enabling precision programmable gain adjustment in high-voltage industrial power supplies.
For engineers reviewing the AD5290YRMZ100 datasheet, AD5290YRMZ100 pinout, AD5290YRMZ100 application, or AD5290YRMZ100 equivalent, this device supports closed-loop voltage control in automotive-grade systems (−40°C to +125°C), offers SPI-compatible 3-wire interface with daisy-chain capability, and provides midscale preset for deterministic startup behavior.
Technical Context
The AD5290YRMZ100 implements a 3-stage segmented RDAC architecture with transmission-gate CMOS wiper switches, enabling monotonic 256-step operation across its full 100 kΩ end-to-end resistance. Its iCMOS™ process supports ±15 V analog terminal voltages while maintaining low 50 μA typical supply current.
It operates in two primary modes: rheostat (two-terminal variable resistor) and potentiometer divider (three-terminal voltage divider). In divider mode, output voltage drift is reduced to 5 ppm/°C due to ratio-based operation, and full-scale error is specified at −2.5 LSB to 0 LSB - critical for high-accuracy DAC replacement applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resistance Value | 100 kΩ nominal, ±30% tolerance at +25°C - defines maximum programmable impedance range and sets current-handling limits (±5 mA continuous). |
| Resolution | 256 positions (8-bit) - enables 0.39% step resolution for fine-grained gain/voltage control in feedback loops. |
| Temperature Coefficient | 35 ppm/°C (resistor), 5 ppm/°C (voltage divider) - ensures stable resistance over −40°C to +125°C automotive range; ratio stability enables precision scaling without calibration. |
| Supply Range | +30 V single supply or ±15 V dual supply - supports direct integration into high-voltage industrial and automotive power rails without level-shifting. |
| THD | 0.002% typical at 1 kHz - meets audio and precision signal-path requirements where harmonic distortion must remain below −94 dB. |
| Interface | 3-wire SPI-compatible (CS, CLK, SDI), open-drain SDO - allows daisy-chaining of multiple units with minimal GPIO usage and no protocol translation. |
| Settling Time | 4 μs to ±1 LSB - enables rapid reconfiguration in closed-loop control systems responding to dynamic load changes. |
Pinout & Package
AD5290YRMZ100 is housed in a compact 3 mm × 3 mm MSOP-10 package with exposed pad for thermal performance. Pin assignments are validated per Analog Devices Rev. D datasheet Figure 4 and Table 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Resistor Terminal A | High-side analog node; supports voltage up to VDD; used with B and W to form programmable divider or rheostat. |
| B | Resistor Terminal B | Low-side analog node; referenced to VSS or GND; defines bottom rail of adjustable resistance path. |
| VSS | Negative Supply | Required for dual-supply operation; tied to 0 V in single-supply mode; establishes analog ground reference. |
| GND | Digital Ground | Separate digital return; must be connected to system ground but kept low-noise to avoid coupling into analog terminals. |
| CS | Chip Select | Active-low enable; rising edge latches serial data into RDAC register; enables multi-device synchronization. |
| CLK | Serial Clock | Positive-edge-triggered; max 4 MHz rate; timing-critical for reliable 8-bit MSB-first data loading. |
| SDI | Serial Data Input | Accepts command/data stream; compatible with standard logic families; requires tDS ≥ 30 ns setup time. |
| SDO | Serial Data Output | Open-drain N-Ch FET; requires external pull-up; shifts out prior frame's SDI for daisy-chain cascading. |
| VDD | Positive Supply | Primary analog power; supports +4.5 V to +33 V; powers internal switches and bias circuitry. |
| W | Wiper Terminal | Programmable tap point; voltage follows code-dependent division ratio between A and B; wiper resistance ≤100 Ω. |
Key Features
| Feature | Design Value |
|---|---|
| Midscale preset on power-up | Automatically initializes wiper to code 0x80 - ensures known, centered output voltage at startup without host MCU intervention. |
| iCMOS™ process technology | Enables ±15 V analog terminal operation with 230°C/W thermal resistance in MSOP-10 - achieves high-voltage robustness without SOIC footprint penalty. |
| Monotonic 256-step operation | Guaranteed ±0.5 LSB DNL across full temperature range - eliminates code-to-code glitches in closed-loop control and filter tuning. |
| 3-wire daisy-chain support | SDO output mirrors prior SDI input - allows synchronous programming of multiple AD5290YRMZ100 units using single SPI bus and one CS line. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5292YRMZ100 | Same 100 kΩ, 256-step, MSOP-10 package; adds EEPROM for nonvolatile wiper setting retention. | Requires persistent state after power loss; not needed if host MCU reinitializes on boot. | Select AD5292YRMZ100 only when power-cycle recovery without host intervention is mandatory. |
| MAX5487ETA+T | 100 kΩ, 256-step, TDFN-8; operates up to +20 V single supply (vs. +30 V); no dual-supply support. | Limited to lower-voltage industrial controls; lacks ±15 V analog rail compatibility. | Choose MAX5487ETA+T only for space-constrained +5 V to +20 V systems where dual-supply operation is unnecessary. |
Compared with AD5290YRMZ100, AD5292YRMZ100 adds nonvolatile memory at the cost of slightly higher quiescent current, while MAX5487ETA+T trades high-voltage capability for smaller footprint - making AD5290YRMZ100 optimal for automotive and industrial designs demanding ±15 V operation and deterministic midscale startup.

FAQ
What is the absolute maximum voltage rating for the A, B, and W terminals of the AD5290YRMZ100?
The A, B, and W terminals of the AD5290YRMZ100 are rated for voltages between VSS and VDD. With VDD = +30 V and VSS = 0 V (single supply), these terminals tolerate 0 V to +30 V. In dual-supply mode (VDD = +15 V, VSS = −15 V), they operate from −15 V to +15 V. Exceeding these bounds forward-biases internal ESD diodes and may cause latch-up or damage. The AD5290YRMZ100 datasheet specifies this in Table 5 Absolute Maximum Ratings.
Does the AD5290YRMZ100 retain its wiper setting after power cycling?
No, the AD5290YRMZ100 does not retain its wiper setting after power cycling. It features volatile memory only: the wiper returns to midscale (code 0x80) on power-up, as defined by its POR (Power-On Reset) circuit. For nonvolatile storage, consider the pin-compatible AD5292YRMZ100, which integrates EEPROM. This behavior is explicitly documented in the AD5290YRMZ100 General Description and Power-Up Sequences sections.
Can the AD5290YRMZ100 be used in a dual-supply configuration with asymmetric rails, such as +24 V and −5 V?
Yes, the AD5290YRMZ100 supports asymmetric dual supplies within its absolute maximum ratings: VDD to VSS must not exceed +35 V, and each supply must stay within −0.3 V to +35 V relative to GND. So +24 V and −5 V (29 V total) is valid. However, analog terminal voltages (A, B, W) must remain between VSS and VDD - meaning −5 V ≤ VA, VB, VW ≤ +24 V. This flexibility is confirmed in the Terminal Voltage Operating Range section of the AD5290YRMZ100 datasheet.
What is the maximum continuous current the AD5290YRMZ100 can handle between its A and B terminals?
The AD5290YRMZ100 supports ±5 mA continuous current between A and B terminals when RWB ≤ 6 kΩ and supply is configured as VDD = +30 V / VSS = 0 V. At 100 kΩ nominal resistance, this corresponds to ≤300 mW power dissipation. Exceeding this risks switch degradation; pulsed current up to ±20 mA is allowed for short durations. These limits are specified in Table 5 Absolute Maximum Ratings and reinforced in the Theory of Operation section of the AD5290YRMZ100 datasheet.
How does the AD5290YRMZ100 achieve 5 ppm/°C voltage divider temperature coefficient when its resistor tempco is 35 ppm/°C?
The AD5290YRMZ100 achieves 5 ppm/°C voltage divider temperature coefficient because the output voltage VW depends on the *ratio* of RWA to RAB (or RWB to RAB), not absolute resistance values. Since both segments track similarly with temperature, their ratio remains stable - reducing drift by ~7× versus single-resistor rheostat mode. This ratio-based stability is intrinsic to potentiometer-divider operation and is measured and guaranteed in the Electrical Characteristics tables for the AD5290YRMZ100.
