Digital Potentiometers datasheet and documents for CAT5221WI-00-QJ

CAT5221WI-00-QJ

Digital Potentiometers Overview

The CAT5221WI-00-QJ is a dual digital potentiometer IC from onsemi, featuring two independent channels with 64 taps each. It utilizes an I2C serial interface for control and includes non-volatile memory to retain wiper settings. The device operates within a supply voltage range of 2.5 V to 6 V and offers a total end-to-end resistance of 100 kOhms per channel. It is housed in a SOIC-20 package and supports linear taper characteristics.

Digital Potentiometers Feature Summary

Integrates two independent digital potentiometers with 64 tap positions each.
Includes non-volatile memory to store up to four wiper settings per channel.
Utilizes a standard I2C serial interface for communication and control.

Digital Potentiometers Applications

Audio volume and tone control systems
Calibration of sensor signals
Adjustable gain control in instrumentation

Digital Potentiometers Procurement Notes

Verify the QJ suffix indicates automotive qualification requirements if applicable. Confirm the 100 kOhm resistance value matches system impedance needs. Ensure I2C address configuration aligns with bus topology. Check moisture sensitivity levels for reflow soldering profiles.

Digital Potentiometers Selection Notes

Select this component when dual-channel adjustment with persistent settings is required. The 100 kOhm resistance suits high-impedance signal paths. The SOIC-20 package provides a balance of pin count and board space. Verify operating temperature ranges against environmental constraints.

Digital Potentiometers Part Context

This part belongs to the CAT5221 series of dual digital potentiometers. It shares architectural similarities with other variants like CAT5221WI-00-T1 but differs in packaging or qualification grades. The series is designed for applications requiring precise, software-controlled resistance adjustment without mechanical wear.
