Product details

Overview

AD5241BRZ10-RL7 from Analog Devices is a single-channel, I²C-compatible 256-position digital potentiometer with 10 kΩ end-to-end resistance, 30 ppm/°C temperature coefficient, and operation from 2.7 V to 5.5 V single supply or ±2.7 V dual supply. It functions as an electronically programmable rheostat or voltage divider in precision gain/offset adjustment circuits for audio, instrumentation, and communications systems.

For engineers reviewing the AD5241BRZ10-RL7 datasheet, AD5241BRZ10-RL7 pinout, AD5241BRZ10-RL7 application, or AD5241BRZ10-RL7 equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin roles, confirmed alternatives, and supply-ready procurement support - all grounded in Analog Devices' Rev. F datasheet and official package documentation.

Technical Context

The AD5241BRZ10-RL7 implements a monolithic 256-tap resistor ladder with wiper controlled via I²C interface (400 kHz max), supporting both rheostat (A–W or B–W) and potentiometer divider (A–W–B) configurations. Its internal power-on midscale preset ensures deterministic startup at code 0x80, and the SHDN pin provides active-low asynchronous shutdown that connects W to B while opening A.

It integrates two programmable logic outputs (O1, O2), each capable of sourcing 40 µA or sinking 1.6 mA, and supports multi-device bus addressing via AD0/AD1 pins. The device maintains monotonicity (±0.4 LSB DNL) and achieves 5 ppm/°C voltage-divider temperature coefficient due to ratio-matched internal resistors.

Key Specifications

Parameter	Value and Actual Design Meaning
Resolution	8-bit (256 positions): enables precise 0.39% step resolution across full 10 kΩ range for fine-grained analog control.
End-to-End Resistance	10 kΩ ±30% at 25°C: matches mechanical potentiometer footprints while enabling digital calibration and remote tuning.
Tempco (RAB)	30 ppm/°C: ensures stable resistance over −40°C to +105°C, critical for industrial sensor conditioning and telecom line drivers.
Wiper Resistance	60 Ω to 120 Ω: contributes fixed offset in low-code settings; limits minimum RWB to 60 Ω at code 0x00, requiring ≤20 mA current to avoid contact degradation.
I²C Interface	400 kHz max clock, 2-wire, readback-capable: allows daisy-chaining up to four devices using AD0/AD1 address bits without external level shifters.
Supply Range	2.7 V to 5.5 V single or ±2.7 V dual: supports mixed-signal systems with 3.3 V controllers and bipolar op-amp stages.
Voltage Divider Tempco	5 ppm/°C: enables high-stability reference division in precision ADC biasing and DAC output scaling where absolute resistance drift is less critical than ratio stability.

Pinout & Package

AD5241BRZ10-RL7 is housed in a 14-lead SOIC package (body width 3.9 mm, JEDEC MS-012AC), RoHS-compliant and tape-and-reel packaged (RL7 suffix). Pin 13 is NC (no connect); all other pins are electrically functional per AD5241 configuration.

Pin/Terminal	Circuit Role	Design Meaning
A1	Resistor Terminal A	High-side terminal of 10 kΩ resistor ladder; open-circuited during SHDN; used with W for rheostat mode or with B for potentiometer mode.
W1	Wiper Terminal	Digitally selectable tap point; output node for voltage division or adjustable resistance path; exhibits 60–120 Ω contact resistance.
B1	Resistor Terminal B	Low-side terminal; tied to W1 during SHDN; serves as reference/ground node in divider mode or return path in rheostat mode.
VDD	Positive Supply	2.7–5.5 V input powering logic core and resistor ladder; also supplies O1/O2 outputs when VSS = GND.
SHDN	Active-Low Shutdown	Asynchronous control: pulls W1 to B1 and opens A1, reducing supply current to ≤0.1 µA while preserving RDAC register contents.
SCL	I²C Clock Input	Accepts standard I²C timing (tLOW ≥1.3 µs, tHIGH ≥0.6 µs); requires external pull-up; tolerant of 5 V logic on 3.3 V systems.
SDA	I²C Data I/O	Open-drain bidirectional line; supports readback of RDAC value; requires external pull-up; shares bus with up to three other AD5241/AD5242 devices.
AD0 / AD1	Address Inputs	Hardwired logic inputs setting 2-bit portion of 7-bit I²C address (01011xx); enable unique addressing for up to four devices on one bus.
DGND	Digital Ground	Reference for I²C interface and logic outputs; must be connected to system ground; separate from analog ground in mixed-signal layouts.
VSS	Negative Supply	Supports ±2.7 V dual supply; enables true bipolar operation (e.g., ±2.5 V op-amp rails); may be tied to DGND for single-supply use.
O2 / O1	Programmable Logic Outputs	Push-pull CMOS outputs; default to logic 0 at power-on; programmable via I²C instruction byte; drive LEDs, analog switches, or logic gates directly.

Key Features

Feature	Design Value
Internal Power-On Midscale Preset	Automatically initializes wiper to code 0x80 (5 kΩ from B1) at power-up, eliminating undefined startup states in gain-control loops.
I²C Readback Capability	Allows host controller to verify programmed wiper position after write, essential for safety-critical calibration and fault logging in medical instruments.
Self-Contained Shutdown	Reduces total current to ≤0.1 µA while retaining register state, enabling ultra-low-power sleep modes in battery-operated sensor nodes.
Extra Programmable Logic Outputs	O1 and O2 provide two independent CMOS outputs-eliminating need for external GPIO expanders in compact audio mixer or test equipment designs.
Extended Temperature Range	Guaranteed operation from −40°C to +105°C supports deployment in automotive engine control modules and industrial PLC I/O cards.

Equivalent & Alternatives

The following parts are listed as comparable options for similar digital potentiometer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP41HV51-103E/SN	10 kΩ, SPI interface, 5.5 V max supply, no dual-supply support, 100 ppm/°C tempco.	Lacks bipolar operation and I²C compatibility; suited for cost-sensitive 3.3 V microcontroller systems without legacy bus constraints.	Select when SPI-native MCU integration is prioritized over multi-device I²C bus sharing and extended temp range.
MAX5487ETE+T	10 kΩ, I²C interface, 2.7–5.5 V supply, 50 ppm/°C tempco, no programmable logic outputs, 16-pin TQFN.	Missing O1/O2 outputs and shutdown pin; smaller footprint but no NC pin for layout flexibility; lower tempco spec not guaranteed over full range.	Choose when board space is critical and auxiliary logic outputs are unnecessary; verify 50 ppm/°C performance meets system drift budget.

Compared with MCP41HV51-103E/SN and MAX5487ETE+T, AD5241BRZ10-RL7 uniquely combines I²C readback, bipolar supply capability, integrated shutdown, and dual logic outputs - making it optimal for industrial diagnostics, audio infrastructure, and systems requiring guaranteed −40°C to +105°C operation with minimal external components.

FAQ

What is the maximum operating temperature for AD5241BRZ10-RL7?

The AD5241BRZ10-RL7 is fully specified and guaranteed to operate from −40°C to +105°C. This extended temperature range is validated per Analog Devices' Rev. F datasheet and applies to all electrical parameters including resistance tolerance, tempco, and I²C timing. The 14-lead SOIC package's thermal resistance (θJA = 158°C/W) supports reliable operation in sealed enclosures without forced airflow when power dissipation remains below 250 µW.

Does AD5241BRZ10-RL7 support dual-supply operation?

Yes, AD5241BRZ10-RL7 supports true dual-supply operation with VDD = +2.7 V and VSS = −2.7 V, enabling bipolar voltage ranges across terminals A1, W1, and B1. This allows AC-coupled signal conditioning and rail-to-rail wiper voltage swing in op-amp circuits. The datasheet specifies all DC and dynamic characteristics under both single-supply (2.7–5.5 V) and dual-supply (±2.7 V) conditions, with no derating required.

Can AD5241BRZ10-RL7 be used in rheostat mode only?

Yes, AD5241BRZ10-RL7 operates reliably in rheostat mode (A1–W1 or B1–W1) with guaranteed monotonicity (±0.4 LSB DNL) and 60–120 Ω wiper resistance. The datasheet provides explicit equations for RWB(D) and RWA(D), and test circuits (Figure 23) validate rheostat performance. Use B1–W1 for low-side current sensing or A1–W1 for high-side gain control, ensuring current stays within 5.0 mA limit for 10 kΩ parts in SOIC packages.

Is the wiper position retained after power cycling AD5241BRZ10-RL7?

No, AD5241BRZ10-RL7 does not include nonvolatile memory; wiper position resets to midscale (code 0x80) on each power-on event due to its internal power-on preset circuit. To retain custom settings across cycles, the host controller must reprogram the RDAC register via I²C after power-up. This behavior is intentional and documented in the "Power-On Preset" section of the Rev. F datasheet.

What is the function of pins O1 and O2 on AD5241BRZ10-RL7?

Pins O1 and O2 are programmable CMOS logic outputs controlled via the I²C instruction byte (bits O1/O2 in Frame 2). They default to logic 0 at power-on and can sink 1.6 mA or source 40 µA - sufficient to drive LEDs, analog switches (e.g., ADG1419), or TTL/CMOS inputs directly. Their states are independent of wiper position and can be updated without altering the RDAC setting, enabling consolidated control of peripheral functions.
