MCP4018T-103E/LTY

Overview

The MCP4018T-103E/LTY is a single-channel, 7-bit volatile digital potentiometer manufactured by Microchip Technology. It features an I2C serial interface and operates within a supply voltage range of 1.8V to 5.5V. The device provides 128 wiper taps with a nominal resistance (RAB) of 10 kΩ (indicated by the '103' suffix). It utilizes RAM for wiper value storage, resetting to mid-scale upon power-up or brown-out events. Key electrical characteristics include a typical wiper resistance of 100 Ω, a bandwidth of 1 MHz at 10 kΩ, and low static current consumption of 2.5 µA.

Feature Summary

7-bit resolution providing 128 discrete wiper positions via I2C interface
Potentiometer configuration with 10 kΩ nominal resistance
Low-power operation with 2.5 µA typical static current
Brown-out reset protection and power-on mid-scale default

Applications

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

Procurement Notes

Verify the ordering suffix 'LTY' corresponds to the SC70-6 package and tape-and-reel shipping format as specified in the manufacturer's datasheet DS20002147B. Confirm that the '103' designation matches the required 10 kΩ resistance value for the specific application design.

Selection Notes

Select this component when a single-channel digital potentiometer with I2C control is required. Ensure the system supports the 1.8V to 5.5V operating range. Note that the memory is volatile; if non-volatile retention is needed across power cycles, consider alternative models such as the MCP40D18 series which feature EEPROM.

Part Context

This part belongs to the MCP4017/18/19 family of 7-bit digital potentiometers. The MCP4018 variant specifically offers a potentiometer pinout, distinguishing it from the rheostat configurations of the MCP4017 and MCP4019. All members of this family share similar electrical characteristics and interface protocols but differ in terminal connectivity.
