MCP4014T-503E/OT

Overview

The MCP4014T-503E/OT is a volatile, single-channel digital potentiometer IC manufactured by Microchip Technology. It features a 6-bit resolution providing 64 taps and a nominal resistance of 50 kΩ. 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 with high-voltage tolerant inputs up to 12.5V. Packaged in a compact SOT-23-5 surface-mount format, it supports rheostat configurations with a typical wiper resistance of 75 Ω and low power consumption.

Feature Summary

6-bit resolution with 64 taps and 50 kΩ nominal resistance
Up/Down (U/D) serial control interface with high-voltage tolerance (up to 12.5V)
Wide operating voltage range: 1.8V to 5.5V
Extended temperature range from -40°C to +125°C

Applications

Variable gain amplifiers
Voltage reference adjustment
Digital volume control circuits
Sensor biasing and calibration

Procurement Notes

Verify the specific suffix 'OT' corresponds to the SOT-23-5 package and reel packaging configuration as defined in the official datasheet. Confirm that the 'E' designation indicates compliance with RoHS standards. Ensure the volatile memory type aligns with system requirements, as settings are lost upon power loss.

Selection Notes

Select this component when a rheostat configuration is required rather than a potentiometer setup. The U/D interface simplifies control logic compared to I2C or SPI protocols. Verify that the 50 kΩ resistance value fits the target circuit impedance and that the 6-bit resolution provides sufficient granularity for the application.

Part Context

This part belongs to the MCP4011/2/3/4 family of low-cost digital potentiometers. The MCP4014 variant is specifically designed for rheostat applications, distinguishing it from the MCP4011 and MCP4013 which support potentiometer modes. The T-503E/OT designation specifies the 50 kΩ resistance value, extended temperature grade, and SOT-23-5 tape-and-reel packaging.
