CAT5113YI-01-26645

Digital Potentiometers Overview

The CAT5113YI-01-26645 is a single-channel digital potentiometer from the onsemi CAT5113 series. It features a 1 kOhm resistance value with a linear taper and 100 tap positions. The device utilizes a non-volatile memory architecture to retain wiper settings without power. Control is managed via a serial 3-wire interface, supporting up/down commands. It operates within a supply voltage range of 2.5 V to 6 V, with typical operation at 3.3 V or 5 V. The component is housed in an 8-pin TSSOP package and is rated for industrial temperatures between -40°C and +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power loss
• Serial 3-wire interface for simplified control
• 100-tap resolution with linear taper
• Single channel with 1 kOhm total resistance

Digital Potentiometers Applications

• Automated gain control in signal processing circuits
• Voltage reference adjustment
• Calibration of sensor bias points
• Volume control in audio equipment

Digital Potentiometers Procurement Notes

Verify the specific suffix '26645' against official onsemi documentation, as standard commercial listings typically use suffixes like '-G'. Confirm availability status, as some CAT5113 variants are marked as obsolete or end-of-life. Ensure the TSSOP-8 package matches the target PCB footprint requirements.

Digital Potentiometers Selection Notes

Select this part when non-volatile storage is required to maintain calibration data. The 1 kOhm value suits low-power applications. Verify that the 3-wire serial interface is compatible with the host microcontroller's available pins. Compare against the CAT5113LI-01-G for PDIP alternatives if through-hole mounting is necessary.

Digital Potentiometers Part Context

This component belongs to the CAT5113 family of non-volatile digital potentiometers. It serves as an electronic replacement for mechanical pots in environments where physical adjustment is impractical. The YI suffix indicates the TSSOP-8 surface-mount package variant.

Digital Potentiometers Replacement Considerations

Direct pin-compatible substitutes include other CAT5113 variants with matching resistance and package, such as CAT5113YI-50-G (50 kOhm). For different resistance values, check CAT5113YI-10-G (10 kOhm) or CAT5113YI-100-G (100 kOhm).
