Overview
The MCP4011-502E/MS is a volatile, 6-bit digital potentiometer manufactured by Microchip Technology in an 8-pin MSOP package. It provides a nominal resistance of 5 kΩ with 64 taps and a linear taper. The device operates on a supply voltage range of 1.8V to 5.5V for logic functions, while resistor characteristics are specified from 2.7V to 5.5V. Control is managed via a simple Up/Down (U/D) serial interface. Key electrical parameters include a typical wiper resistance of 75 Ω, a maximum static current of 1 µA, and high-voltage tolerant inputs up to 12.5V.
Feature Summary
- 6-bit resolution offering 64 discrete tap positions with a linear resistance taper.
- Up/Down (U/D) serial control interface compatible with standard microcontrollers.
- High-voltage tolerant digital inputs allowing operation up to 12.5V regardless of VDD.
- Low power consumption with a maximum static current of 1 µA.
Applications
- Volume control in audio signal processing circuits.
- Programmable gain amplifiers requiring adjustable resistance ratios.
- Voltage reference trimming and calibration systems.
- Digital potentiometer replacement for mechanical pots in space-constrained PCBs.
Procurement Notes
Verify the specific suffix 'E' indicates extended temperature range (-40°C to +125°C) and 'MS' denotes the 8-lead MSOP package. Confirm RoHS compliance status through official Microchip documentation or authorized distributors prior to ordering. Ensure design accounts for volatile memory behavior where settings reset upon power loss.
Selection Notes
Select this component when a single-channel, 5 kΩ digital potentiometer with U/D interface is required. Compare against MCP4012 if rheostat configuration is preferred. Consider MCP4013 or MCP4014 variants only if different pinouts or packaging options like SOT-23 are necessary for the specific layout constraints.
Part Context
This part belongs to the MCP401x family of low-cost, 6-bit digital potentiometers. The family includes MCP4011 (Potentiometer), MCP4012 (Rheostat), MCP4013 (Potentiometer), and MCP4014 (Rheostat). All share identical electrical specifications but differ in terminal configurations and available packages such as SOT-23, SOIC, MSOP, and DFN.
Replacement Considerations
Direct functional substitutes within the same family include MCP4011-502E/SN (SOIC-8 package). For rheostat applications, MCP4012-502E/MS is electrically equivalent but configured differently. Verify package dimensions and pinout compatibility before substituting across different package types.
