CAT5115VI-00-GT3

Digital Potentiometers Overview

The CAT5115VI-00-GT3 is a single digital potentiometer IC from onsemi, featuring 32 linear taps and a nominal resistance of 100 kΩ. It operates on a single supply voltage ranging from 2.5 V to 6.0 V with a standby current of 1 µA maximum. The device utilizes an up/down serial interface controlled by CS, U/D, and INC pins to adjust the wiper position across the resistor array. Packaged in an SOIC-8 (V suffix) with NiPdAu lead finish, it is RoHS compliant and halogen-free. The wiper resets to tap 15 upon power-up, as the position is not stored in volatile memory.

Digital Potentiometers Feature Summary

• 32-position linear taper potentiometer with 100 kΩ nominal resistance
• Single supply operation from 2.5 V to 6.0 V
• Up/Down serial control interface using CS, U/D, and INC pins
• SOIC-8 package with industrial temperature range (-40°C to +85°C)

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibrations

Digital Potentiometers Procurement Notes

Verify the 'V' suffix indicates the SOIC-8 package and 'I' denotes the industrial temperature range. Confirm the '00' suffix corresponds to the 100 kΩ resistance value. Ensure the 'GT3' suffix matches the required tape and reel shipping quantity of 3000 units. Check for RoHS compliance status if environmental regulations apply to the specific manufacturing batch.

Digital Potentiometers Selection Notes

Select this component when a non-volatile memory storage is not required, as the wiper position resets to tap 15 at power-up. For applications needing power-on recall, consider the CAT5114 series instead. Verify that the 100 kΩ resistance value fits the circuit design requirements and that the 32-tap resolution is sufficient for the desired adjustment granularity.

Digital Potentiometers Part Context

This part belongs to the CAT5115 family of 32-tap digital potentiometers. The 'V' suffix specifies the SOIC-8 package, while 'Y' and 'Z' denote TSSOP-8 and MSOP-8 packages respectively. The 'I' suffix indicates the industrial temperature grade. Other variants include different resistance values (10 kΩ, 50 kΩ) and the CAT5114 which includes non-volatile memory for wiper retention.

Digital Potentiometers Replacement Considerations

For pin-compatible replacement without memory retention, use other CAT5115 variants with different resistance values or packages. If power-on wiper recall is necessary, substitute with the CAT5114 series. Ensure the alternative device supports the same 2.5 V to 6.0 V supply range and up/down control interface.
