X9317ZM8

Digital Potentiometers Overview

The X9317ZM8 is a single-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It features a total 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. It operates on a serial 3-wire interface (U/D, INC, CS) and supports a supply voltage range of 4.5 V to 5.5 V. The typical operating current is 50 uA, and it functions within an ambient temperature range of 0°C to +70°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 100-tap resolution with linear taper characteristic
• Low power consumption with 50 uA typical operating current
• Serial 3-wire compatible interface for control

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Calibration of sensor signals

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for moisture sensitivity handling requirements during storage and assembly. Validate package integrity against the specified tube packaging format.

Digital Potentiometers Selection Notes

Select this component when a 1 kOhm resistance value and 100-step resolution are required. Ensure the system operates within the 4.5 V to 5.5 V supply range. Consider the industrial temperature range if environmental conditions exceed standard commercial limits. Verify that the serial interface logic levels match the controlling microcontroller.

Digital Potentiometers Part Context

This part belongs to the X9317 family of digitally controlled potentiometers. Variants in this series differ primarily in resistance values (e.g., 1k, 10k, 50k, 100k), package types (SOIC, TSSOP, MSOP), and temperature grades. The Z suffix typically denotes specific tape and reel or tube packaging options depending on the distributor catalog.

Digital Potentiometers Replacement Considerations

Cross-reference with other X9317 variants such as X9317WS8Z or X9317UV8IZ for different resistance values or packages. Ensure pin compatibility and electrical specifications match before substitution.
