CAT5112ZI-10-GT3

Digital Potentiometers Overview

The CAT5112ZI-10-GT3 is a single-channel digital potentiometer IC manufactured by onsemi. It features a 10 kOhm resistance value with 32 taps and utilizes non-volatile memory to retain settings. The device operates on a serial interface and supports power supply voltages of 3.3 V and 5 V, with a maximum operating voltage of 6 V and minimum of 2.5 V. It draws 200 uA of operating current and functions within a temperature range of -40 C to +85 C. The component is housed in an MSOP-8 surface-mount package.

Digital Potentiometers Feature Summary

• Single digital potentiometer with 10 kOhm resistance and 32 tap positions
• Non-volatile memory retains wiper position after power loss
• Operates at 3.3 V or 5 V with 200 uA typical current consumption
• Available in compact MSOP-8 SMD package

Digital Potentiometers Applications

• Automated adjustments on high volume production lines
• Equipment requiring periodic adjustment in hazardous or remote environments
• Electronic replacement for mechanical potentiometers

Digital Potentiometers Procurement Notes

Verify the end-of-life status before procurement as the component is marked as obsolete. Confirm the specific suffix GT3 matches the required reel quantity of 3000 units. Ensure the MSOP-8 package dimensions align with the target PCB footprint. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Digital Potentiometers Selection Notes

Select this part when a single channel with 10 kOhm resistance and 32 steps is required. The non-volatile feature is essential for applications needing state retention without battery backup. The MSOP-8 package suits space-constrained designs compared to larger SOIC options. Verify that the 3-wire serial interface compatibility exists with the host controller.

Digital Potentiometers Part Context

This component belongs to the CAT5112 series of digital potentiometers from onsemi. It serves as a direct electronic alternative to mechanical pots, offering durability and programmability. The ZI-10-GT3 designation specifies the 10 kOhm resistance, industrial temperature grade, and tape-and-reel packaging format.

Digital Potentiometers Replacement Considerations

Direct substitutes include other CAT5112 variants with different resistance values or packages, such as CAT5112WI-10TE13 (SOIC-8) or CAT5112YI-10-GT3. Cross-model comparisons should focus on matching the 32-tap count, non-volatile memory type, and 10 kOhm resistance value.
