X9317ZS8-2.7

Digital Potentiometers Overview

The X9317ZS8-2.7 is a single-channel digital potentiometer from the Renesas XDCP series, housed in an 8-SOIC surface-mount package. It features a nominal resistance of 1 kOhm with a linear taper and 100 tap positions for precise adjustment. The device utilizes non-volatile memory to retain wiper settings upon power loss and operates via a simple Up/Down (U/D), Increment (INC), and Chip Select (CS) serial interface. It supports a supply voltage range of 2.7 V to 5.5 V, with a typical contact resistance of 200 Ohms and a temperature coefficient of ±300 ppm/°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 100-tap resolution with linear taper for accurate control
• Low power consumption with 50 µA operating current
• Simple 3-wire serial interface (U/D, INC, CS)

Digital Potentiometers Applications

• Audio volume control and tone adjustment circuits
• Programmable gain amplifiers in signal conditioning
• Voltage reference trimming and calibration
• LCD bias voltage adjustment

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as older batches may not meet current environmental standards. Check for end-of-life notifications or obsolescence warnings prior to procurement planning.

Digital Potentiometers Selection Notes

Select this model for applications requiring 1 kOhm resistance with linear response. Ensure the operating voltage falls within the 2.7 V to 5.5 V range. Consider the 8-SOIC package dimensions for PCB layout constraints. Verify that the ±20% tolerance meets circuit accuracy requirements.

Digital Potentiometers Part Context

Part of the X9317 family of digital potentiometers, offering various resistance values and package options. The 'Z' suffix typically indicates lead-free/RoHS compliant variants, while 'S8' denotes the SOIC-8 package. This specific variant targets low-power, space-constrained designs requiring persistent resistance settings.

Digital Potentiometers Replacement Considerations

Direct pin-to-pin replacements include other X9317 variants with matching resistance (e.g., X9317WV8) or package types. Cross-reference with Intersil ISL8217M series if available. Verify interface compatibility and voltage ranges before substitution.
