CAT5111ZI10

Digital Potentiometers Overview

The CAT5111ZI-10 is a single digital potentiometer from onsemi, housed in an MSOP-8 package. It features a 10 kΩ linear taper resistor array with 100 tap positions and a buffered wiper output. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V. Wiper position control utilizes a three-pin serial interface (CS, U/D, INC), and the setting is retained in non-volatile EEPROM memory upon power loss.

Digital Potentiometers Feature Summary

• 100-position linear taper digital potentiometer with 10 kΩ resistance
• Non-volatile EEPROM storage for wiper position retention
• Buffered wiper output using rail-to-rail op amp
• Three-wire incremental up/down serial interface

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibrations
• Programmable analog functions

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'ZI' corresponds to the MSOP-8 package with Matte-Tin lead finish as defined in the manufacturer's documentation. Confirm that the '-T3' shipping designation matches the required tape and reel quantity of 3000 units for production integration.

Digital Potentiometers Selection Notes

Select this component when a buffered wiper output is required for driving external loads without affecting the internal resistor divider ratio. Ensure the application requires non-volatile memory to maintain settings across power cycles. Verify that the 100-tap resolution and 10 kΩ total resistance align with the circuit design specifications.

Digital Potentiometers Part Context

This part belongs to the CAT5111 family of 100-tap digital potentiometers. The 'Z' suffix indicates the MSOP-8 package variant, while 'I' denotes the industrial temperature range (-40°C to +85°C). The '10' specifies the 10 kΩ resistance value. Other variants include SOIC, TSSOP, and PDIP packages.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include CAT5111VI-10-G (SOIC-8) and CAT5111LI-10-G (PDIP-8). For applications requiring unbuffered outputs, consider the CAT5113 series. Verify package dimensions and lead finishes when substituting.
