MCP4011-502E/SN

Overview

The MCP4011-502E/SN is a volatile, 6-bit digital potentiometer manufactured by Microchip Technology. It features 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 and 2.7V to 5.5V for resistor characteristics. It utilizes a simple Up/Down (U/D) serial interface for wiper control. 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. The component is housed in an 8-pin SOIC package and supports an extended operating temperature range from -40°C to +125°C.

Feature Summary

• 6-bit resolution providing 64 discrete tap positions with a linear taper.
• Simple 2-wire Up/Down (U/D) serial interface for wiper adjustment.
• High-voltage tolerant digital inputs capable of handling up to 12.5V.
• Low-power operation with a maximum static current of 1 µA.

Applications

• Volume control in audio circuits.
• Gain adjustment in instrumentation amplifiers.
• Voltage reference trimming.
• Programmable biasing in analog front-ends.

Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-Narrow-8 package when sourcing. Confirm the '-502' designation matches the required 5 kΩ resistance value. Ensure the volatile memory type aligns with system power-loss requirements, as settings are not retained without external non-volatile storage solutions.

Selection Notes

Select this model for applications requiring a single-channel digital potentiometer with low pin count. The 5 kΩ resistance value is suitable for moderate impedance circuits. Consider the MCP4012 or MCP4014 if rheostat configuration is preferred over potentiometer mode, or if different package constraints apply.

Part Context

This component belongs to the MCP4011/2/3/4 family of low-cost, 64-step volatile digital potentiometers. The MCP4011 variant specifically offers a potentiometer configuration. Other family members like the MCP4012 provide rheostat functionality, while variations exist in package types such as SOT-23 and DFN.

Replacement Considerations

Direct replacements within the same family include the MCP4011-503E/SN (50 kΩ) or MCP4011-103E/SN (10 kΩ) for identical interfaces and packages with different resistance values. Cross-family alternatives require verification of interface compatibility and pinout alignment.
