MCP41050T-E/SN

Digital Potentiometers Overview

The MCP41050T-E/SN is a single-channel, 8-bit digital potentiometer manufactured by Microchip Technology. It features a nominal resistance of 50 kΩ with 256 discrete tap positions 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. It includes a software shutdown feature that disconnects the A terminal and connects the wiper to the B terminal for power savings. The component is housed in an 8-pin SOIC package and is specified for industrial temperature ranges.

Digital Potentiometers Feature Summary

• Single-channel digital potentiometer with 50 kΩ nominal resistance
• 256-position resolution controlled via SPI serial interface
• Low power consumption with <1 µA static supply current
• Software shutdown mode for maximum power efficiency

Digital Potentiometers Applications

• Audio equipment volume and tone control
• Servo motor control systems
• Battery charging and management circuits
• Communication line impedance matching
• Instrumentation gain and offset adjustment

Digital Potentiometers Procurement Notes

Verify the ordering suffix 'T' indicates tape and reel packaging and 'E' denotes the extended temperature range variant (-40°C to +125°C). Confirm the 'SN' suffix corresponds to the 8-lead SOIC package. Ensure compatibility with the required SPI clock frequency and voltage levels before procurement.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with 50 kΩ resistance is required. The 8-bit resolution provides 256 steps suitable for precise analog adjustments. Consider the MCP42050 if dual-channel functionality or hardware shutdown pins are needed instead of software-controlled shutdown.

Digital Potentiometers Part Context

This part belongs to the MCP41XXX/42XXX family of digital potentiometers. The MCP41XXX series specifically designates single-channel devices, while the MCP42XXX series offers dual channels. The MCP41050 variant specifically provides the 50 kΩ resistance option within this architecture.

Digital Potentiometers Replacement Considerations

MCP41050-I/SN: Industrial temperature range variant (-40°C to +85°C). MCP41050-E/MS: Extended temperature range in MSOP-8 package. MCP42050: Dual-channel version with similar electrical characteristics.
