X9251TV24Z-2.7S2705

Digital Potentiometers Overview

The X9251TV24Z-2.7 is a quad digitally-controlled potentiometer (XDCP) manufactured by Intersil, now part of Renesas Electronics. It features four independent potentiometers, each with 256 tap positions and a resistance value of 100 kOhms. The device utilizes a serial SPI interface for control and includes non-volatile memory to retain wiper settings upon power loss. It operates on a single supply voltage ranging from 2.7 V to 5.5 V, with a typical operating current of 400 uA. The component is available in a TSSOP-24 package and supports linear taper characteristics.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 100 kOhm potentiometers
• 256 tap positions per potentiometer for precise adjustment
• Non-volatile memory retains wiper position after power cycle
• SPI serial interface for digital control

Digital Potentiometers Applications

• Variable gain amplifier control
• Voltage reference adjustment
• System calibration and trimming

Digital Potentiometers Procurement Notes

Verify the manufacturer status as Intersil has been acquired by Renesas Electronics. Confirm the specific suffix 'S2705' against official datasheets or distributor catalogs to ensure it denotes a valid tape-and-reel variant or specific packaging code, as standard listings often use suffixes like '-2.7' or 'T1'. Check RoHS compliance documentation for the specific batch.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with high resistance values (100 kOhm) and non-volatile storage is required. Ensure the system interface supports SPI communication. Verify that the 2.7 V to 5.5 V supply range aligns with the target application's power rails. Consider the TSSOP-24 package size constraints during PCB layout.

Digital Potentiometers Part Context

This part belongs to the X9251 series of quad digitally-controlled potentiometers. It is functionally similar to other variants such as X9251TV24IZ-2.7 and X9251TS24ZT1, differing primarily in package type (TSSOP vs SOIC) and manufacturing lot codes. The series is designed for low-power, single-supply applications requiring adjustable resistance via digital commands.

Digital Potentiometers Replacement Considerations

Direct replacements include X9251TV24IZ-2.7 and X9251TS24ZT1 from Renesas/Intersil. Cross-manufacturer equivalents should be verified for pin compatibility, resistance tolerance, and interface protocol. Ensure the substitute maintains the 100 kOhm resistance and 256-tap resolution.
