CAT5113VI-10-GT3

Digital Potentiometers Overview

The CAT5113VI-10-GT3 is a single digital potentiometer IC from onsemi, featuring a 10 kΩ resistance value with 100 linear taper positions. It operates on a single supply voltage ranging from 2.5 V to 6.0 V and draws a standby current of 10 nA. The device utilizes non-volatile EEPROM memory to retain the wiper setting during power-down, automatically restoring it upon power-up. Control is managed via an Increment/Up-Down serial interface using CS, U/D, and INC pins. It is housed in an SOIC-8 package (V suffix) and supplied in tape and reel format (GT3 suffix).

Digital Potentiometers Feature Summary

• 100-position linear taper potentiometer with 10 kΩ nominal resistance.
• Non-volatile EEPROM storage retains wiper position after power loss.
• Ultra-low standby current of 10 nA for energy-efficient operation.
• Increment/Up-Down serial control interface requiring only three pins.

Digital Potentiometers Applications

• Automated product calibration and tamper-proof calibrations.
• Remote control adjustments for inaccessible or hazardous environments.
• Offset, gain, and zero control in instrumentation circuits.
• Programmable analog functions such as contrast, brightness, and volume controls.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffixes against the manufacturer's documentation to ensure correct package type and shipping quantity. The 'V' suffix indicates an SOIC-8 package, while 'GT3' denotes tape and reel packaging. Confirm that the industrial temperature range (-40°C to +85°C) meets system requirements. Check for end-of-life status or obsolescence notices directly from onsemi before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when a non-volatile digital potentiometer with 100 taps is required. Ensure the application voltage stays within the 2.5 V to 6.0 V range. The SOIC-8 package is suitable for surface-mount assembly. Compare wiper current limits and linearity errors if high precision is needed. Consider alternative packages like TSSOP or MSOP if space constraints differ, adjusting the part number suffix accordingly.

Digital Potentiometers Part Context

This part belongs to the CAT5113 family of 100-tap digital potentiometers. Variants exist with different resistance values (1 kΩ, 50 kΩ, 100 kΩ) and packages (PDIP, SOIC, TSSOP, MSOP). The VI-10 designation specifically identifies the 10 kΩ version in the SOIC-8 package. Other family members may share similar electrical characteristics but differ in physical dimensions or resistance ranges.

Digital Potentiometers Replacement Considerations

Direct replacements must match the 100-tap count, non-volatile memory, and SOIC-8 package. Verify pin compatibility for CS, U/D, INC, RH, RW, RL, VCC, and GND. Cross-reference with other manufacturers offering similar SPI or I2C compatible digital pots, ensuring voltage ranges and standby currents are comparable.
