ISL90727WIE627Z-T7A

Digital Potentiometers Overview

The ISL90727WIE627Z-T7A is a volatile solid-state digital potentiometer manufactured by Renesas Electronics. It integrates an array of 128 wiper taps, each comprising a resistor element and a sliding switch, controlled via an I2C serial bus interface. The device operates within a terminal voltage range of 2.7V to 5.5V and supports RTOTAL values of 10kΩ or 50kΩ. It features low-power CMOS technology with a maximum active current of 200μA and standby current of 500nA. The unit is housed in a compact 6-lead SC-70 package.

Digital Potentiometers Feature Summary

• I2C serial bus interface for digital control of wiper position
• 128 wiper taps providing precise resistance adjustment
• Low power consumption: 200μA active, 500nA standby
• Available in 10kΩ and 50kΩ total resistance options

Digital Potentiometers Applications

• Replacement for mechanical potentiometers
• Sensor calibration for pressure, temperature, and optical sensors
• RF amplifier biasing
• LCD brightness and contrast adjustment
• Gain control and offset adjustment circuits

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T7A' against official Renesas documentation to confirm tape and reel packaging quantities and moisture sensitivity levels. Ensure the selected RTOTAL value (10kΩ or 50kΩ) matches the circuit requirements, as this parameter may vary across different suffixes within the ISL90727 family.

Digital Potentiometers Selection Notes

Select this component when a non-volatile memory solution is not required, as the device is volatile and resets to mid-scale upon power-up. Confirm that the system can accommodate the I2C communication protocol and that the SC-70 package dimensions fit the PCB layout constraints. Verify the operating temperature range meets the -40°C to +85°C specification.

Digital Potentiometers Part Context

This part belongs to the ISL90727/ISL90728 series of digital controlled potentiometers (XDCP). These devices are designed to replace traditional mechanical potentiometers in applications requiring remote or automated adjustment. The series utilizes a CMOS process to achieve low power consumption while maintaining high reliability and precision through its resistive array structure.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. When evaluating alternatives, ensure compatibility with the I2C interface, 128-tap resolution, and SC-70-6 package footprint.
