MCP4152-104E/MS

Digital Potentiometers Overview

The MCP4152-104E/MS is a single-channel digital potentiometer IC from Microchip Technology, housed in an 8-pin MSOP package. It features an 8-bit resolution providing 256 tap positions and a nominal resistance (R_AB) of 100 kΩ with a ±20% tolerance. The device utilizes a volatile memory architecture controlled via a high-speed SPI serial interface operating at up to 10 MHz. It supports a wide supply voltage range of 1.8V to 5.5V and operates within an extended temperature range of -40°C to +125°C.

Digital Potentiometers Feature Summary

• Single resistor network with 8-bit resolution (256 steps) and 100 kΩ nominal resistance.
• SPI serial interface supporting modes 0,0 and 1,1 with clock frequencies up to 10 MHz.
• High-voltage tolerant digital inputs capable of withstanding up to 12.5V.
• Operates on a single supply voltage ranging from 1.8V to 5.5V.

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'MS' corresponds to the MSOP-8 package when sourcing components. Confirm that the 'E' suffix indicates compliance with RoHS standards and halogen-free requirements as specified by the manufacturer for this part number.

Digital Potentiometers Selection Notes

Select the MCP4152-104E/MS for applications requiring a single rheostat or potentiometer configuration with 100 kΩ resistance. Ensure the system design accommodates volatile memory behavior, as wiper settings are lost upon power loss. Verify that the host microcontroller supports the required SPI protocol and voltage levels.

Digital Potentiometers Part Context

This component belongs to the MCP41XX family of single-channel digital potentiometers. It shares architectural similarities with other devices in the MCP413X, MCP414X, and MCP416X series, differing primarily in resolution, memory type (RAM vs. EEPROM), and specific pin configurations.

Digital Potentiometers Replacement Considerations

Direct replacements include other variants within the MCP415X series, such as MCP4151-104E/MS for a potentiometer configuration. Cross-family alternatives like the MCP4252 offer dual-channel functionality but require different pinout considerations.
