ISL28486FAZ

Overview

The ISL28486FAZ is a quad micropower single-supply rail-to-rail input and output (RRIO) precision operational amplifier manufactured by Renesas Electronics Corporation. It features a gain bandwidth product of 400 kHz, a slew rate of 0.17 V/µs, and an input bias current of 500 pA. The device operates within a supply voltage range of 3 V to 40 V, drawing a typical operating supply current of 270 µA. It provides a common-mode rejection ratio of 102 dB and an input voltage noise density of 15.8 nV/√Hz. Packaged in a 16-lead QSOP, it supports stable closed-loop gains up to approximately 400.

Feature Summary

• Quad channel configuration with rail-to-rail input and output capabilities for maximum dynamic range.
• Micropower operation draws minimal supply current while maintaining DC accuracy and low noise specifications.
• High precision performance characterized by ultra-low input bias current and high common-mode rejection ratio.

Applications

• Precision signal conditioning in battery-powered instrumentation
• Active filtering applications requiring stable closed-loop gains
• Low-power sensor interface circuits

Procurement Notes

Verify the specific package variant, as the base part number may correspond to different suffixes such as FAZ or T7. Confirm RoHS compliance status and check for end-of-life notifications, as some listings indicate obsolescence. Ensure the supplier documentation matches the exact pinout and electrical characteristics required for your design.

Selection Notes

Select this component when designing systems that require multiple precision amplifiers with strict power consumption limits. The RRIO feature makes it suitable for single-supply applications where signal swing must approach the rails. Consider the 400 kHz bandwidth and 0.17 V/µs slew rate for moderate-speed signal processing tasks.

Part Context

This component belongs to the ISL284xx series of micropower op-amps from Renesas, which includes dual and quad variants. The series is designed to offer a balance between low power consumption and high precision, targeting portable and industrial applications. It complements other precision analog components in the Renesas portfolio for complete signal chain solutions.
