Product details
Overview
MCP4011-503E/SN from Microchip Technology is a volatile 6-bit digital potentiometer in SOT-23-6 package, configured as a potentiometer with 64 taps, 50 kΩ nominal resistance, ±20% tolerance, and 75 Ω typical wiper resistance. It operates from 1.8V to 5.5V, supports up/down serial interface, and is used for precision gain/offset trimming in sensor signal conditioning circuits.
For engineers reviewing the MCP4011-503E/SN datasheet, MCP4011-503E/SN pinout, MCP4011-503E/SN application, or MCP4011-503E/SN equivalent, key selection criteria include its 50 kΩ resistance value, SOT-23-6 footprint, 125°C extended temperature rating, low 1 µA static current, and high-voltage tolerant U/D inputs up to 12.5V.
Technical Context
The MCP4011-503E/SN implements a resistor ladder with digitally controlled wiper position via simple up/down (U/D) serial protocol - no clock or data lines beyond CS and U/D. Its volatile RAM wiper register resets to mid-scale (0x1F) on power-up, and it supports both potentiometer (three-terminal) and rheostat (two-terminal) configurations by floating A or B.
It features high-voltage input thresholds (VIHH ≥ 8.5V) enabling direct connection to 12V control signals without level-shifting, while maintaining full compatibility with 1.8V–5.5V logic. The device exhibits ratiometric tempco of 10 ppm/°C in potentiometer mode and absolute tempco of 150 ppm/°C over –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Resistance | 50 kΩ ±20% - defines full-scale analog range for voltage divider or bias network design |
| Resolution | 64 taps (6-bit) - enables 1.56% step resolution across total resistance |
| Wiper Resistance | 75 Ω typical - limits insertion error and signal attenuation at wiper output |
| Operating Voltage | 1.8V to 5.5V - supports single-supply operation in battery-powered and mixed-voltage systems |
| Temperature Range | –40°C to +125°C - qualified for automotive under-hood and industrial motor-control environments |
| Bandwidth | 200 kHz (–3 dB, 50 kΩ device) - suitable for DC and low-frequency analog adjustment, not RF |
| Static Current | 1 µA max - enables ultra-low-power trimming in always-on sensor front-ends |
Pinout & Package

| 3 (B) | Resistor Terminal B | Fixed end of resistor array; typically grounded or connected to return path |
| 4 (CS) | Chip Select | Active-low enable for U/D commands; high-voltage tolerant (up to 12.5V) |
| 5 (U/D) | Up/Down Control | Edge-triggered direction input; high = increment wiper, low = decrement; HV-tolerant |
| 6 (VSS) | Ground | Logic and analog ground reference; must be low-impedance for stable wiper performance |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5160BRJZ-50-R7 | Nonvolatile EEPROM wiper memory; SPI interface; 50 kΩ; SOT-23-8 package | Retains setting after power loss; requires SPI host instead of simple U/D GPIO | Select if persistent wiper state is required and SPI resources are available |
| MCP4017-503E/SN | Volatile 7-bit (128-step) resolution; same SOT-23-6 package; identical 50 kΩ value and 125°C rating | Higher resolution for finer analog tuning; otherwise pin- and function-compatible | Select if improved step granularity (0.78% vs. 1.56%) improves system accuracy |
Compared with AD5160BRJZ-50-R7, MCP4011-503E/SN offers simpler GPIO-based control and lower cost but lacks nonvolatility; compared with MCP4017-503E/SN, it provides adequate resolution for most trimming tasks at reduced complexity and price.

FAQ
What is the nominal resistance and tolerance of the MCP4011-503E/SN?
The MCP4011-503E/SN has a nominal resistance of 50 kΩ with a tolerance of ±20%, as specified in the Electrical Characteristics table for the "–503" device variant. This value represents the resistance between terminals A and B at 25°C and VDD = 2.7V–5.5V. The tolerance accounts for process variation and is confirmed across the full operating temperature range.
Does the MCP4011-503E/SN retain its wiper setting after power cycling?
No, the MCP4011-503E/SN is a volatile digital potentiometer and does not retain its wiper setting after power removal. Upon power-up, it automatically recalls the default mid-scale setting (0x1F, or decimal 31). Custom power-on wiper values require factory programming and are not supported for standard-orderable MCP4011-503E/SN units.
Can the MCP4011-503E/SN be used in rheostat mode?
Yes, the MCP4011-503E/SN can operate in rheostat mode by leaving either terminal A or B unconnected (floating), using only two terminals (e.g., A and W, or B and W). In this configuration, it functions as a digitally adjustable variable resistor, supporting applications like LED current limiting or bias current adjustment.
What is the maximum allowable voltage on the U/D and CS pins of the MCP4011-503E/SN?
The U/D and CS pins of the MCP4011-503E/SN tolerate voltages up to 12.5V with respect to VSS, independent of VDD. This high-voltage tolerance allows direct interfacing with 5V or 12V microcontrollers without external level-shifting circuitry, simplifying system design and improving robustness.
What package type and footprint does the MCP4011-503E/SN use?
The MCP4011-503E/SN uses the SOT-23-6 package: a 6-pin, surface-mount, gull-wing outline measuring 2.8 mm × 1.6 mm × 1.1 mm. It is RoHS-compliant, lead-free, and rated MSL1 - suitable for standard reflow assembly without moisture preconditioning.
