ISL22323WFV14Z-TK

Digital Potentiometers Overview

The ISL22323WFV14Z-TK is a dual digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features two independent circuits, each with 256 taps and a resistance value of 10 kΩ. The device utilizes an I²C serial interface for control and incorporates non-volatile memory to retain wiper settings upon power loss. It operates within a supply voltage range of ±2.25V to 5.5V and supports optional address selection. The component is housed in a 14-TSSOP package and is rated for operation between -40°C and +125°C.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 256 discrete tap positions per circuit
• Non-volatile memory retains wiper position after power cycle
• I²C serial interface with optional hardware address selection
• Linear taper configuration with ±20% resistance tolerance

Digital Potentiometers Applications

• Industrial control systems requiring adjustable gain or offset
• Programmable voltage reference circuits
• Audio volume control applications

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TK' against the manufacturer's official datasheet to confirm packaging details and any functional distinctions from standard tube versions. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary.

Digital Potentiometers Selection Notes

Select this component when a dual-channel digital potentiometer with non-volatile storage and I²C connectivity is required. Ensure the 10kΩ resistance value and 256-tap resolution meet the circuit's precision requirements. Verify that the operating temperature range of -40°C to +125°C aligns with the application environment.

Digital Potentiometers Part Context

This part belongs to the ISL22323 family of XDCP™ devices. It is functionally similar to other variants in the series but differs in packaging and interface specifics. The 'WFV14Z' designation indicates the 14-lead TSSOP package and lead-free construction, while 'TK' typically denotes tape and reel packaging.

Digital Potentiometers Replacement Considerations

Direct replacements include other ISL22323 variants with compatible pinouts and specifications. Verify that substitute parts maintain the same I²C addressing scheme and non-volatile memory functionality to ensure seamless integration.
