CAT5112VI-10-GT3

Digital Potentiometers Overview

The CAT5112VI-10-GT3 is a single-channel digital potentiometer IC manufactured by onsemi. It features a non-volatile memory architecture that retains the wiper setting after power loss, ensuring data integrity without continuous power supply. The device offers 32 discrete tap positions with a linear taper characteristic and a nominal resistance of 10 kOhms. It operates within a supply voltage range of 2.5 V to 6 V and draws a typical operating current of 100 uA. Communication is handled via a standard 3-wire serial interface supporting up/down commands. The component is housed in an SOIC-8 surface-mount package and is rated for operation between -40°C and +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position upon power cycle
• 32-tap linear taper digital potentiometer with 10 kOhm resistance
• 3-wire serial interface for up/down control
• Integrated output buffer for improved drive capability

Digital Potentiometers Applications

• Audio volume control circuits requiring persistent settings
• Programmable gain amplifiers in instrumentation systems
• Voltage reference adjustment in embedded systems
• Calibration of sensor signal conditioning paths

Digital Potentiometers Procurement Notes

Verify the specific suffix 'G' against official datasheets to confirm lead-free compliance status. Confirm availability as distribution channels may list this part as discontinued or limited stock. Ensure the SOIC-8 package variant matches the design footprint requirements before procurement.

Digital Potentiometers Selection Notes

Select this component when non-volatile storage is required for the resistance setting. Compare against volatile counterparts like the CAT5110 if power consumption during standby is critical, noting the higher current draw associated with non-volatile operations. Ensure the 10 kOhm value fits the circuit impedance constraints.

Digital Potentiometers Part Context

This part belongs to the CAT511x family of digital potentiometers from onsemi. It shares the 32-tap architecture with other members but distinguishes itself through the inclusion of non-volatile memory and an integrated output buffer, differentiating it from the volatile CAT5110 series.

Digital Potentiometers Replacement Considerations

Direct replacements include the CAT5112YI-10-GT3 (TSSOP-8 package) or CAT5112VI-10-G (tube packaging). Verify pin compatibility and package dimensions when substituting.
