ISL23325TFVZ-T7A

Digital Potentiometers Overview

The ISL23325TFVZ-T7A is a dual-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It features two independent potentiometers with linear taper and 256 tap positions each. The total resistance for each channel is 100 kOhms with a tolerance of 20%. The device operates on a supply voltage ranging from 1.7 V to 5.5 V and consumes a typical operating current of 18 uA. It utilizes an I2C serial interface for control and employs volatile brush memory to retain wiper settings during operation.

Digital Potentiometers Feature Summary

• Dual-channel configuration with 256 taps per potentiometer
• I2C serial interface for digital control
• Linear taper with 100 kOhms nominal resistance
• Wide supply voltage range of 1.7 V to 5.5 V

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Sensor biasing and calibration

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with I2C bus protocols and check for moisture sensitivity level (MSL) requirements during storage and handling. Confirm that the volatile memory architecture aligns with system power-loss recovery strategies.

Digital Potentiometers Selection Notes

Select this component when a dual-channel digital potentiometer with high resolution (256 steps) and low power consumption is required. The 100 kOhms resistance value suits applications requiring moderate impedance levels. Verify that the I2C addressability meets system bus constraints and that the TSSOP-14 package fits the PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the ISL23325 family of digital potentiometers. The TFVZ designation indicates a TSSOP-14 package variant. The T7A suffix typically denotes a specific reel quantity or packaging format within the Intersil/Renesas product line, distinct from tube-packaged variants like the base ISL23325TFVZ.

Digital Potentiometers Replacement Considerations

Direct replacements include other ISL23325 variants with compatible pinouts and electrical characteristics. Cross-model substitutes from the same family may require verification of package dimensions and I2C command set compatibility.
