ISL28533FVZ-T7A

Overview

The ISL28533FVZ-T7A is a dual micro-power, high-precision operational amplifier from the Renesas Intersil ISL28633 series. It features rail-to-rail input and output capabilities, supporting single supply voltages from 2.5 V to 5.5 V or dual supplies of ±1.25 V to ±2.75 V. Key electrical characteristics include a maximum input offset voltage of 10 µV, a minimum common-mode rejection ratio (CMRR) of 80 dB, and a gain-bandwidth product of 3 MHz. The device operates within a temperature range of -40 °C to +125 °C with a maximum supply current of 3.5 mA.

Feature Summary

• High precision with low input offset voltage
• Rail-to-rail input and output operation
• Micro-power consumption design

Applications

• Instrumentation systems
• Signal conditioning circuits
• Buffer amplifiers

Procurement Notes

Verify the specific suffix 'T7A' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Renesas Electronics Corporation, noting the historical Intersil branding often associated with this component lineage. Ensure the package type matches the required 14-pin TSSOP form factor for your PCB layout constraints.

Selection Notes

Select this component for applications requiring high accuracy in low-voltage environments. The rail-to-rail I/O allows for maximum dynamic range in single-supply systems. Consider the 3 MHz bandwidth and 3.5 mA current draw for power-sensitive designs that still demand precision signal processing capabilities.

Part Context

This part belongs to the ISL28633 series of instrumentation and operational amplifiers. It represents a transition from Intersil to Renesas Electronics Corporation product lines. The device is designed for general-purpose analog signal chain applications where size and power efficiency are critical alongside precision performance.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the ISL28xxx family. Verify equivalent specifications such as offset voltage and bandwidth before substituting with other manufacturers' parts.
