X9317ZV8I-2.7

Digital Potentiometers Overview

The X9317ZV8I-2.7 is a single-channel digital potentiometer from the Renesas XDCP series, housed in an 8-VSSOP package. It features a resistance value of 50 kOhms with 100 taps and linear taper characteristics. The device operates on a supply voltage range of 2.7 V to 5.5 V and utilizes a non-volatile memory architecture to retain wiper settings upon power loss. Control is achieved via a simple Up/Down (U/D), Increment (INC), and Chip Select (CS) serial interface. Key electrical parameters include a typical contact resistance of 400 Ohms and a temperature coefficient of ±300 ppm/°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• Single circuit configuration with 100 resistive taps
• Linear taper for precise resistance adjustment
• Low power consumption with 50 µA operating current

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• System calibration and offset nulling

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified suppliers. Confirm RoHS compliance status and check for recent Product Change Notices (PCNs) regarding labeling or fabrication site updates. Ensure storage conditions adhere to moisture sensitivity level (MSL) ratings to prevent package damage during soldering.

Digital Potentiometers Selection Notes

Select this model when a 50 kOhm resistance range is required with non-volatile retention capabilities. The 8-VSSOP package is suitable for space-constrained surface-mount designs. Verify that the system supply voltage falls within the 2.7 V to 5.5 V operational window and that the control logic levels are compatible with the U/D, INC, and CS interface signals.

Digital Potentiometers Part Context

This component belongs to the X9317 family of digitally controlled potentiometers, which offers various resistance values and package options. The 'Z' suffix typically denotes specific environmental or packaging variations within the Renesas portfolio. It serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance without moving parts.

Digital Potentiometers Replacement Considerations

Direct pin-to-pin replacements may include other X9317 variants with different resistance values (e.g., 10k, 100k) or packages (e.g., TSSOP, MSOP). Ensure the substitute part matches the 50 kOhm resistance and non-volatile requirement. Cross-reference datasheets for interface compatibility and thermal performance differences.
