MCP4011T-503E/SN

Overview

The MCP4011T-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. Designed for surface-mount applications, 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
• Wide operating voltage range from 1.8V to 5.5V

Applications

• Volume control circuits
• Gain adjustment stages
• Voltage reference trimming
• Sensor biasing adjustments

Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging and the 'SN' suffix specifies the SOIC-8 package. Confirm the 'E' suffix denotes the extended industrial temperature grade (-40°C to +125°C). Ensure the datasheet DS20001978D is referenced for accurate pinout and electrical specifications during integration.

Selection Notes

Select this component when a volatile memory type is acceptable, as settings are lost upon power loss. The 50 kΩ resistance value suits moderate impedance applications. Verify that the 1 MHz toggle frequency meets system timing requirements. Consider the 75 Ω typical wiper resistance for signal path integrity.

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 be optimized for rheostat use. The T-503E designation identifies the specific resistance value, packaging, and temperature grade within this product line.

Replacement Considerations

Direct replacements include other MCP4011 variants with different resistance values or packages, such as MCP4011-103E/SN (10 kΩ) or MCP4011-503E/MS (SOIC-8 MSOP). Cross-family substitutes like MCP41010 require SPI interfaces and are not pin-compatible.
