X9118TV14IZ

Digital Potentiometers Overview

The X9118TV14IZ is a single-channel digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics. It features a resistance value of 100 kOhms with a linear taper and 1024 tap positions. The device utilizes a 2-wire serial interface for control and includes non-volatile memory to retain wiper settings. It operates within a supply voltage range of 4.5 V to 5.5 V, drawing a typical operating current of 3 mA. The component is housed in a 14-pin TSSOP package and supports surface mount installation. It functions reliably across an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors. Verification of authenticity and storage conditions is critical due to the discontinued status. Ensure compatibility with existing designs before procurement.

Digital Potentiometers Selection Notes

Select this part when a high-resolution 100 kOhm digital potentiometer with non-volatile storage is required. Verify that the system operates at 5V, as lower voltage variants like the X9118TV14Z-2.7 support 2.7V but may have different thermal ratings. Confirm that the 2-wire interface aligns with the host controller's capabilities rather than SPI or I2C alternatives.

Digital Potentiometers Part Context

The X9118 belongs to the XDCP family of digitally controlled potentiometers. It shares architectural similarities with other models in the series but differs in interface type and voltage specifications. The 'IZ' suffix typically denotes specific packaging and environmental compliance attributes within the Renesas product line.

Digital Potentiometers Replacement Considerations

Direct replacements are limited due to the obsolete status. Consider the X9118TV14Z-2.7 for dual-supply (2.7V–5.5V) applications, noting the extended commercial temperature range (0°C to +70°C). For SPI interfaces, evaluate the X9110 series. Verify pinout and electrical parameters against datasheets before substitution.
