ISL23328TFVZ-T7A

Digital Potentiometers Overview

The ISL23328TFVZ-T7A is a dual, volatile, low-voltage digitally controlled potentiometer (DCP) featuring an I2C bus interface. It provides two independent potentiometers with 128 taps each and a nominal resistance of 100 kOhms. The device operates within a supply voltage range of 1.7V to 5.5V and supports an industrial temperature range of -40°C to +85°C. Packaged in a 14-TSSOP format, it offers low noise and low power consumption characteristics suitable for precision analog control applications.

Digital Potentiometers Feature Summary

• Dual channel configuration with 128-tap resolution per potentiometer
• I2C serial interface for digital wiper position control
• Low voltage operation compatible with 1.7V to 5.5V supplies
• Volatile memory architecture retaining settings only during power

Digital Potentiometers Applications

• Precision gain adjustment in instrumentation amplifiers
• Voltage reference trimming in data acquisition systems
• Programmable filter frequency setting in signal processing
• Bias current adjustment in sensor interfaces

Digital Potentiometers Procurement Notes

Verify the specific suffix T7A indicates tape and reel packaging when sourcing. Confirm the 14-TSSOP package dimensions against your PCB footprint requirements. Check for RoHS compliance status as manufacturing sources may vary. Ensure the I2C address configuration matches your system bus topology before integration.

Digital Potentiometers Selection Notes

Select this component when dual independent digital pots are required in a compact surface-mount package. The 100kOhm resistance value suits moderate impedance circuits. Consider the volatile nature if non-volatile storage is needed for power-down states. Verify the I2C speed compatibility with your microcontroller controller.

Digital Potentiometers Part Context

This part belongs to the ISL23328 series of XDCP devices from Renesas. It shares core specifications with variants like ISL23328WFVZ but differs in package type and termination style. The TFVZ designation specifically denotes the 14-lead thin shrink small-outline package variant within the broader dual DCP family.

Digital Potentiometers Replacement Considerations

Direct substitutes include ISL23328WFRUZ-TK or ISL23328TFRUZ-T7A depending on package preference. Cross-reference pinouts carefully as package changes may alter terminal arrangements. Verify electrical parameters remain identical to ensure circuit compatibility.
