X93156UM8I-2.7

Digital Potentiometers Overview

The X93156UM8I-2.7 is a single digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, formerly Intersil. It features a 50 kΩ total resistance with 32 wiper tap points and a linear taper. The device operates on a supply voltage range of 2.7V to 5.5V and utilizes an Up/Down interface for control. Key specifications include a typical active current of 200µA at 5V and a standby current of 2µA maximum. The component incorporates nonvolatile memory to retain the wiper position upon power cycling. It is housed in an 8-lead Mini Small Outline Plastic Package (MSOP).

Digital Potentiometers Feature Summary

• Single-channel digital potentiometer with 50kΩ end-to-end resistance and 32 taps.
• Up/Down control interface using CS, U/D, and INC inputs.
• Nonvolatile memory retains wiper position after power loss.
• Operates within a 2.7V to 5.5V supply voltage range.
• Low power consumption: 200µA typical active current, 2µA max standby.

Digital Potentiometers Applications

• Programming bias voltages in electronic circuits.
• LCD brightness and contrast control.
• Implementation of ladder networks.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as Pb-free variants exist with specific suffixes. Check for moisture sensitivity level (MSL) requirements prior to surface mount assembly. Ensure ordering suffixes match required voltage ranges and packaging formats.

Digital Potentiometers Selection Notes

Select this model for applications requiring a 50kΩ resistance value and 2.7V minimum operating voltage. Compare against the X93156WM8I-2.7 if a 12.5kΩ resistance is needed instead. Consider the X93156UM8IZ-2.7 variant if lead-free (RoHS compliant) termination finishes are mandatory for the manufacturing process.

Digital Potentiometers Part Context

The X93156 belongs to the XDCP family of digitally controlled potentiometers from Renesas/Intersil. It shares architectural similarities with the X9315 series but differs in resistance values and specific interface configurations. This component represents a solid-state alternative to mechanical potentiometers, offering programmable resistance without moving parts.

Digital Potentiometers Replacement Considerations
