Product details
Overview
AD5262BRUZ200-RL7 from Analog Devices is a dual-channel, 256-position, 200 kΩ digital potentiometer operating from 5 V to 15 V single supply or ±5.5 V dual supply. It provides independently programmable rheostat/potentiometer functions with 35 ppm/°C temperature coefficient, SPI-compatible 4-wire interface, and power-on midscale preset. It replaces mechanical potentiometers in precision gain/offset adjustment circuits.
For engineers reviewing the AD5262BRUZ200-RL7 datasheet, AD5262BRUZ200-RL7 pinout, AD5262BRUZ200-RL7 application, or AD5262BRUZ200-RL7 equivalent, key selection criteria include dual-channel independence, 200 kΩ end-to-end resistance, 15 V absolute maximum terminal voltage, ±5 mA continuous wiper current rating, and TSSOP-16 package compatibility with industrial temperature range (−40°C to +85°C).
Technical Context
The AD5262BRUZ200-RL7 implements two independent 256-step resistor ladders with wiper terminals (W1/W2), each controlled by a 9-bit serial register including address bit A0. Its RDAC architecture supports both potentiometer divider mode (VA–W–VB) and rheostat mode (A–W or B–W), with monotonic 8-bit resolution and guaranteed ±½ LSB INL.
It features daisy-chainable SDO output, active-low PR (preset to 0x80), SHDN (open-circuit A terminals, W→B), and logic supply VL decoupled from analog supplies VDD/VSS. Terminal voltage range spans VSS to VDD, supporting bipolar AC/DC operation up to ±13 V across A/B/W pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual, independently programmable RDACs - enables stereo audio level control or matched gain/offset tuning in differential signal paths. |
| End-to-End Resistance | 200 kΩ ±30% - sets full-scale voltage division ratio and defines minimum load impedance for stable DAC-like operation. |
| Resolution | 8-bit (256 positions) - delivers 0.39% step resolution for fine analog parameter adjustment without microcontroller interpolation. |
| Tempco | 35 ppm/°C (RAB) - ensures resistance stability over −40°C to +85°C, critical for instrumentation calibration accuracy. |
| Supply Range | Single: 4.5 V to 16.5 V; Dual: ±4.5 V to ±5.5 V - supports direct integration into 12 V/15 V industrial rails and ±5 V op-amp signal chains. |
| Interface | SPI-compatible 4-wire (CS, CLK, SDI, SDO) - enables simple microcontroller connection with no protocol translation; 25 MHz max clock. |
| Wiper Current | ±5 mA continuous - allows direct drive of low-impedance loads (e.g., op-amp feedback networks) without external buffering. |
Pinout & Package
AD5262BRUZ200-RL7 is housed in a 16-lead TSSOP package (4.4 mm × 5.0 mm, 0.65 mm pitch), RoHS-compliant and moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SDO) | Serial Data Output | Open-drain output requiring external pull-up; enables daisy-chaining multiple AD5262 devices without decoding logic. |
| 2 (A1), 4 (B1), 3 (W1) | RDAC1 Terminals | A1/W1/B1 form first 200 kΩ variable resistor; W1 position set by 9-bit code with A0 = 0. |
| 16 (A2), 14 (B2), 15 (W2) | RDAC2 Terminals | A2/W2/B2 form second independent 200 kΩ resistor; W2 position set when A0 = 1 in serial word. |
| 5 (VDD), 12 (VSS), 11 (GND) | Analog Power Rails | VDD/VSS support ±5.5 V dual or 15 V single supply; GND is digital/analog common reference point. |
| 13 (VL) | Logic Supply | Decouples digital interface voltage (2.7 V–5.5 V) from analog supplies - prevents noise coupling into RDAC ladder. |
| 9 (CS), 7 (CLK), 8 (SDI) | SPI Interface Inputs | CS active-low enables register load on rising edge; CLK positive-edge clocks 9-bit word (A0 + D7–D0); SDI accepts MSB-first data. |
| 6 (SHDN), 10 (PR) | Control Inputs | SHDN (active low) opens A1/A2 and shorts W1→B1/W2→B2; PR (active low) forces both wipers to midscale (0x80). |
Key Features
| Feature | Design Value |
|---|---|
| 200 kΩ End-to-End Resistance | Enables high-impedance voltage divider configurations with minimal loading on source signals - ideal for sensor biasing and reference scaling. |
| Independent Dual-Channel Control | Allows simultaneous but non-interacting adjustment of two signal paths - e.g., left/right channel gain in audio or differential offset trimming. |
| Power-On Midscale Preset | Guarantees known 100 kΩ wiper position at startup - eliminates undefined output states and simplifies system initialization sequences. |
| ±5 mA Wiper Current Rating | Supports direct connection to op-amp feedback nodes or current-setting resistors without external drivers - reduces BOM count and layout area. |
| 35 ppm/°C Temperature Coefficient | Ensures <±0.3% resistance drift over full industrial temperature range - meets requirements for factory-calibrated test equipment and medical sensors. |
Applications
| Instrumentation Gain Adjustment | Stereo Audio Level Control |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5262BRUZ50-RL7 | Same dual-channel architecture and pinout, but 50 kΩ end-to-end resistance. | Better suited for lower-impedance signal paths (e.g., op-amp feedback with <10 kΩ sources) where 200 kΩ would cause bandwidth loss. | Select when circuit bandwidth >100 kHz is required or when driving capacitive loads <100 pF. |
| MAX5487ETE+ | Single-channel, 100 kΩ, I²C interface, 14-lead TSSOP - not pin-compatible; different logic voltage tolerance (1.7–5.5 V). | Applicable where space-constrained designs require single-channel control and I²C bus sharing is preferred over SPI. | Choose only if dual-channel independence is unnecessary and I²C infrastructure already exists. |
Compared with AD5262BRUZ200-RL7, the AD5262BRUZ50-RL7 offers higher bandwidth and lower thermal noise but reduced voltage division range, while the MAX5487ETE+ sacrifices channel count and pin compatibility for I²C simplicity and lower supply voltage flexibility.

FAQ
What is the maximum supply voltage the AD5262BRUZ200-RL7 can withstand?
The AD5262BRUZ200-RL7 supports a single-supply range of 4.5 V to 16.5 V and dual-supply operation up to ±5.5 V. Absolute maximum ratings specify VDD to GND ≤ +17 V and VDD to VSS ≤ 17 V, with terminal voltages (A/B/W) limited to VSS and VDD. Exceeding these violates reliability specifications.
Does the AD5262BRUZ200-RL7 retain its wiper setting during power-down?
Yes - the AD5262BRUZ200-RL7 retains its programmed resistance value in the RDAC latch during shutdown mode. When SHDN is asserted (low), A1/A2 terminals open-circuit and W1/W2 connect to B1/B2, but the internal 9-bit latch contents remain unchanged, restoring exact prior settings upon exit from shutdown.
Can the AD5262BRUZ200-RL7 be used in bipolar AC signal paths?
Yes - the AD5262BRUZ200-RL7 supports true bipolar operation: VA, VB, and VW may swing from VSS to VDD regardless of polarity. With ±5 V supplies, it handles ±5 V AC signals in potentiometer mode; datasheet Figure 19 confirms stable zero-scale error across −40°C to +85°C under bipolar conditions.
What is the purpose of the VL pin on the AD5262BRUZ200-RL7?
The VL pin supplies power to the digital interface circuitry (SPI logic, shift register, decode logic) independently from analog supplies VDD/VSS. It must be tied to the same voltage as the controlling MCU's I/O rail (2.7 V–5.5 V). This separation prevents digital switching noise from modulating the analog RDAC ladder, preserving THD and crosstalk performance.
How does the AD5262BRUZ200-RL7 handle daisy-chaining multiple devices?
The AD5262BRUZ200-RL7 uses an open-drain SDO pin (Pin 1) that outputs the last bit shifted out of its serial register. By connecting SDO of one device to SDI of the next, and using a shared CS/CLK, up to N devices can be cascaded with a single SPI bus - eliminating GPIO expansion and reducing firmware complexity versus individual chip selects.
