MCP4011-503E/SN

Overview

The MCP4011-503E/SN is a volatile, 6-bit digital potentiometer manufactured by Microchip Technology. It features a 50 kΩ resistance value with 64 taps and operates within a supply voltage range of 1.8V to 5.5V. The device utilizes a simple Up/Down (U/D) serial interface for wiper control and includes high-voltage tolerant inputs capable of handling up to 12.5V. It 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
• High-voltage tolerant U/D and CS inputs up to 12.5V
• Low static current consumption of 1 µA maximum
• Extended temperature operation from -40°C to +125°C

Applications

• Volume control in audio circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Programmable biasing networks

Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-8 package when sourcing. Confirm that the 'E' designation indicates compliance with RoHS standards. Ensure the application design accounts for the volatile memory nature of the device, as settings are lost upon power removal.

Selection Notes

Select this component for applications requiring a single-channel digital potentiometer with high-voltage input tolerance. The 50 kΩ resistance value suits moderate impedance circuits. Consider the volatile memory characteristic if power-on state consistency is required without external non-volatile storage.

Part Context

This part belongs to the MCP4011/2/3/4 family of low-cost digital potentiometers. The MCP4011 variant specifically offers potentiometer configuration options, whereas other family members may offer rheostat configurations or different pinouts. All variants share similar electrical characteristics and interface protocols.

Replacement Considerations

Direct replacements within the same family include MCP4011-503E/MS (MSOP package) or MCP4011-503E/MC (DFN package). Cross-family replacements like MCP4101 require SPI interfaces and differ in memory type.
