X9116WS8ZT1

Digital Potentiometers Overview

The X9116WS8ZT1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single potentiometer with 16 wiper taps and a total resistance of 10 kOhms. The device utilizes a serial 3-wire interface for control and includes non-volatile memory to retain the last wiper position upon power-up. It operates within a supply voltage range of 2.7V to 5.5V, with a typical operating current of 150 uA. The component is housed in an 8-SOIC surface-mount package and is rated for commercial temperatures from 0°C to +70°C.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile 16 wiper taps with linear taper
• 3-wire up/down serial interface for tap position control
• Non-volatile memory stores wiper position for recall at power-up
• Operates on 2.7V to 5.5V supply with low active current

Digital Potentiometers Applications

• Trimmer applications replacing mechanical potentiometers
• Circuit calibration requiring variable resistance
• Audio volume control systems
• Gain adjustment in signal processing circuits

Digital Potentiometers Procurement Notes

The X9116WS8ZT1 is listed as obsolete and no longer manufactured by Renesas Electronics Corporation. Availability is restricted to existing stock or third-party distributors. Verification of authenticity and storage conditions is critical due to the end-of-life status. Designers should consider alternative components for new production runs.

Digital Potentiometers Selection Notes

Select this component only if legacy compatibility is required. Ensure the design supports the 2.7V to 5.5V supply range. Verify that the 8-SOIC package dimensions fit the PCB layout. Note that the device has a ±20% resistance tolerance and a temperature coefficient of ±300ppm/°C. Confirm that the 16-tap resolution meets the application's precision requirements.

Digital Potentiometers Part Context

This part belongs to the X9116 series of Digitally Controlled Potentiometers. It is functionally similar to other variants like the X9116WM8ZT1 but differs in packaging (SOIC vs. MSOP) and specific electrical characteristics such as contact resistance. The 'Z' suffix typically indicates RoHS compliance, and 'T1' denotes tape and reel packaging.

Digital Potentiometers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, designers must evaluate pin-compatible alternatives or redesign the circuit to accommodate different packages or interfaces.
