CAT5112VI-00-G

Digital Potentiometers Overview

The CAT5112VI-00-G is a single-channel digital potentiometer featuring a buffered wiper output. It provides 32 linear tap positions with a nominal resistance of 100 kΩ between the high (RH) and low (RL) terminals. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V and consumes a maximum supply current of 200 µA during increment operations. Wiper position data is retained in non-volatile EEPROM, ensuring settings are preserved during power cycles. Control is managed via a three-pin serial interface consisting of Chip Select (CS), Up/Down (U/D), and Increment (INC).

Digital Potentiometers Feature Summary

• Buffered wiper output using rail-to-rail op amp technology.
• Non-volatile EEPROM storage for wiper position recall upon power-up.
• Increment/Up-Down serial control interface requiring only three pins.
• Industrial temperature range operation from -40°C to +85°C.

Digital Potentiometers Applications

• Automated product calibration systems.
• Remote control adjustments for inaccessible equipment.
• Offset, gain, and zero control circuits.
• Tamper-proof calibration applications.
• Programmable analog functions such as contrast or volume controls.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'VI' confirms the SOIC-8 surface-mount package and '-00' indicates the 100 kΩ resistance value. Confirm that the 'GT3' designation implies tape and reel packaging if required for automated assembly processes. Ensure the industrial grade ('I') meets the thermal requirements of the target environment.

Digital Potentiometers Selection Notes

Select this component when a buffered output is necessary to drive loads without affecting the internal resistor ladder linearity. Compare against the CAT5114 if a two-terminal variable resistor configuration is preferred, as the buffered wiper is not compatible with that specific application mode. Verify that the 32-tap resolution meets the system's adjustment granularity requirements.

Digital Potentiometers Part Context

This part belongs to the CAT5112 family of 32-tap digital potentiometers manufactured by onsemi. The 'V' suffix specifically denotes the SOIC-8 package variant, while the 'I' indicates industrial temperature rating. Other variants include PDIP, TSSOP, and MSOP packages with different resistance values denoted by the numeric suffixes.
