X9429WV14IZ-2.7

Digital Potentiometers Overview

The X9429WV14IZ-2.7 is a single-channel digital potentiometer from the XDCP™ series, manufactured by Renesas Electronics Corporation. It features a 10 kΩ resistance value with 64 taps and utilizes an I2C serial interface for control. The device operates within a supply voltage range of 2.7 V to 5.5 V and includes non-volatile memory to retain wiper positions. Packaged in a 14-TSSOP surface-mount case, it supports linear taper configurations and offers optional address settings for multi-device systems.

Digital Potentiometers Feature Summary

• I2C Serial Interface: Utilizes two-wire communication for register-oriented direct read/write/transfer of wiper positions.
• Non-Volatile Memory: Retains up to four stored wiper positions per potentiometer without power.
• Wide Supply Range: Operates on VCC and V+ supplies from 2.7 V to 5.5 V.
• Linear Taper: Provides a linear resistance profile with ±20% tolerance.

Digital Potentiometers Applications

• Audio volume control and tone adjustment circuits.
• Programmable gain amplifier biasing.
• Variable voltage reference generation.
• Sensor calibration and offset trimming.

Digital Potentiometers Procurement Notes

This component is officially listed as End-of-Life (EOL) with a discontinuation date of December 23, 2016. Verification of RoHS compliance indicates conformity with ROHS3 standards. Buyers should confirm availability through authorized distributors or secondary markets, as standard manufacturing has ceased. Cross-reference datasheets for pin compatibility before sourcing substitutes.

Digital Potentiometers Selection Notes

Select this part for applications requiring a single digital potentiometer with I2C connectivity and non-volatile storage. Ensure the system voltage aligns with the 2.7 V to 5.5 V operating range. Verify that the 14-TSSOP package fits the PCB footprint. Consider the ±20% resistance tolerance and ±300ppm/°C temperature coefficient for precision requirements.

Digital Potentiometers Part Context

Part of the X9429 family within the XDCP™ line, designed for low-power CMOS applications. It shares architectural similarities with other X94xx series devices but differs in interface type (I2C vs. SPI) and channel count. The 'IZ' suffix typically denotes industrial temperature range and RoHS compliance, while '-2.7' specifies the minimum supply voltage rating.

Digital Potentiometers Replacement Considerations

Direct replacements include X9429WV14IZ-2.7T1 (tape and reel packaging) or X9429WV14I-2.7 (non-RoHS version). For SPI interface alternatives, consider the X9420 series. Verify pinout compatibility and memory architecture when substituting with other digital potentiometers.
