MCP42050-E/P

Digital Potentiometers Overview

The MCP42050-E/P is a dual-channel digital potentiometer manufactured by Microchip Technology in an industrial temperature range variant. It features two independent 50 kΩ potentiometers, each with 256 linear taps controlled via an SPI serial interface. The device operates on a single supply voltage ranging from 2.7V to 5.5V and consumes less than 1 µA in static operation. Key electrical specifications include a typical wiper resistance of 175 Ω at 5.5V and a nominal resistance tolerance of ±30%. The component supports hardware shutdown and reset functions, ensuring low power consumption and reliable state management within the -40°C to +85°C operating range.

Digital Potentiometers Feature Summary

• 256-tap resolution with linear taper controlled via SPI interface
• Hardware Shutdown (SHDN) and Reset (RS) pins for power management
• Industrial temperature range specification (-40°C to +85°C)

Digital Potentiometers Applications

• Replacing mechanical potentiometers in volume control circuits
• Programmable gain amplifier configurations
• Voltage reference adjustment systems

Digital Potentiometers Procurement Notes

Verify the 'E' suffix indicates the extended or specific industrial grade variant as defined by Microchip documentation. Confirm package integrity for the 14-pin PDIP form factor upon receipt. Ensure compatibility with system voltage levels before integration.

Digital Potentiometers Selection Notes

Select this model when dual-channel control is required with 50 kΩ resistance values. The PDIP package is suitable for through-hole mounting applications. Verify that the SPI interface mode (0,0 or 1,1) aligns with the host controller's configuration requirements.

Digital Potentiometers Part Context

This component belongs to the MCP42XXX family of dual digital potentiometers. It shares functional similarities with the MCP42010 and MCP42100 but differs in nominal resistance values. The 'I' suffix typically denotes industrial range, while 'E' may indicate specific regional or manufacturing variants requiring datasheet confirmation.

Digital Potentiometers Replacement Considerations

Direct substitutes include other MCP42050 variants with different packaging suffixes such as MCP42050-I/SL or MCP42050-T/E/ML. Cross-family replacements like MCP41050 offer single-channel functionality only.
