CAT5132ZGI-10

Digital Potentiometers Overview

The CAT5132ZGI-10 is a single-channel digital potentiometer from onsemi, featuring 128 linear taps and an I2C serial interface. It operates with a digital supply voltage (VCC) of 2.7 V to 5.5 V and an analog supply range (V+) of +8 V to +16 V. The device includes non-volatile memory for wiper setting storage, ensuring automatic recall at power-up. Key electrical parameters include a 10 kΩ end-to-end resistance, 300 PPM/°C temperature coefficient, and 20% tolerance. It functions as an electronic replacement for mechanical potentiometers in industrial applications.

Digital Potentiometers Feature Summary

• I2C Interface: Serial bus control for wiper adjustment and data register access.
• Non-Volatile Memory: Stores wiper settings with a 100-year retention guarantee.
• High Voltage Operation: Supports analog supply up to +16 V for high-voltage applications.
• Linear Taper: Provides 128 equal resistive elements for precise step-wise adjustment.

Digital Potentiometers Applications

• LCD Screen Adjustment
• Volume Control
• Gain Adjustment
• Line Impedance Matching
• VCOM Setting Adjustments

Digital Potentiometers Procurement Notes

Verify the specific suffix 'ZGI' against official onsemi documentation to confirm package type and tape/reel specifications. Confirm current availability status as product lifecycles may change. Ensure compliance with RoHS and halogen-free requirements if specified for the target application environment.

Digital Potentiometers Selection Notes

Select this component when a high-voltage digital potentiometer with I2C control is required. The 10 kΩ resistance value suits moderate current applications. Verify that the system logic levels are compatible with the 2.7 V to 5.5 V VCC range. Consider the MSOP-10 package constraints for PCB layout and thermal management.

Digital Potentiometers Part Context

This part belongs to the CAT5132 family of 16 Volt Digitally Programmable Potentiometers. It shares core functionality with variants like CAT5132ZI-10 but differs in packaging or ordering suffix details. The series is designed to replace mechanical pots in automated production lines and remote equipment.

Digital Potentiometers Replacement Considerations

Direct substitutes within the same family include CAT5132ZI-10. Verify pin compatibility and electrical ratings before substitution. Check for any differences in non-volatile memory behavior or I2C addressing between specific suffixes.
