CAT5115LI-10-G

Digital Potentiometers Overview

The CAT5115LI-10-G is a single-channel digital potentiometer IC manufactured by onsemi. It features a linear taper resistance of 10 kOhms with 32 discrete taps for precise adjustment. The device operates within a supply voltage range of 2.5 V to 6 V and consumes a typical operating current of 100 uA. It utilizes a volatile brush memory and communicates via a serial 3-wire interface. Designed for through-hole mounting, it is housed in an 8-pin PDIP package and supports an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Single digital potentiometer with 10 kOhm linear taper and 32 tap positions
• Serial 3-wire up/down control interface for wiper position adjustment
• Volatile brush memory retains settings only during power
• Operates on 2.5 V to 6 V supply with 100 uA typical current consumption

Digital Potentiometers Applications

• Automated gain control in instrumentation systems
• Volume or tone control in audio equipment
• Calibration of sensor signal conditioning circuits
• Voltage reference adjustment in test and measurement devices

Digital Potentiometers Part Context

This component belongs to the CAT5115 series of 32-tap digital potentiometers. While other variants exist in different packages such as SOIC-8 (VI) or TSSOP-8 (YI), the LI suffix specifically denotes the PDIP-8 through-hole package. This series serves as an electronic replacement for mechanical potentiometers in applications requiring remote or automated adjustment capabilities.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pinout compatibility and electrical specifications when considering alternative digital potentiometer ICs from other manufacturers.
