ISL28197FRUZ-T7

Comparators Overview

The ISL28197FRUZ-T7 is a precision, low-power operational amplifier manufactured by Renesas Electronics. It features a rail-to-rail output stage and operates from a single supply voltage ranging from 2.5V to 5.5V. The device offers a typical input offset voltage of 30µV and a maximum bias current of 2pA at 25°C. It provides a gain-bandwidth product of 1MHz and a slew rate of 0.6V/µs. Packaged in an 8-lead TSSOP with thermal pad, it is designed for high-accuracy applications requiring low power consumption and minimal signal distortion.

Comparators Feature Summary

• Rail-to-rail output capability ensures maximum dynamic range in single-supply systems.
• Ultra-low input bias current minimizes errors in high-impedance sensor interfaces.
• Precision matching and low offset voltage support high-accuracy data acquisition tasks.

Comparators Applications

• Portable medical instrumentation
• Battery-powered measurement devices
• Industrial process control sensors

Comparators Procurement Notes

Verify the exact suffix 'T7' indicates tape-and-reel packaging when ordering. Confirm the 'FRUZ' package designation matches the required 8-lead TSSOP footprint with exposed pad. Ensure the manufacturer is Renesas Electronics Corporation to avoid counterfeit components. Check for RoHS compliance markings on the datasheet or shipping documentation.

Comparators Selection Notes

Select this component when single-supply operation is required alongside rail-to-rail output swing. Consider its low bias current for interfacing with high-impedance sources such as pH electrodes or piezoelectric sensors. Evaluate the 1MHz bandwidth against system speed requirements to ensure adequate phase margin and stability in feedback configurations.

Comparators Part Context

This part belongs to the ISL281xx series of precision op-amps. It shares architectural similarities with other members like the ISL28196 but differs in specific electrical characteristics such as offset voltage and bias current specifications. The series is targeted at portable and battery-operated applications where power efficiency and accuracy are critical design constraints.

Comparators Replacement Considerations

Direct pin-compatible substitutes may include other Renesas ISL281xx variants with similar electrical specs. Cross-reference with competitors like TI OPA333 or ADI ADA4522 only if pinout and package dimensions match exactly. Verify that replacement parts meet the same rail-to-rail output and low bias current requirements.

Comparators FAQ

Is the ISL28197FRUZ-T7 unity-gain stable?
