X9319UP8I

Digital Potentiometers Overview

The X9319UP8I is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single circuit with a total resistance of 10 kOhms and 100 taps for precise adjustment. The device utilizes non-volatile memory to retain the wiper setting upon power loss. It operates on a 5V supply voltage and communicates via an Up/Down interface using U/D, INC, and CS signals. The component is housed in an 8-PDIP package and supports a linear taper configuration.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 100-tap resolution with 10 kOhm total resistance
• Simple Up/Down control interface (U/D, INC, CS)
• Linear taper characteristic

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming

Digital Potentiometers Part Context

This component belongs to the X9319 series of digital potentiometers from Renesas. The 'UP' suffix indicates an 8-pin PDIP package variant. It is part of the broader XDCP family designed for replacing mechanical potentiometers in applications requiring programmable resistance.

Digital Potentiometers Replacement Considerations

Direct replacement options include other X9319 series variants with different packaging or resistance values, such as X9319WS8I (SOIC package) or X9317 series devices if resistance tolerance allows. Verify pin compatibility and package dimensions when substituting.
