ISL28433FVZ-T13

Overview

The ISL28433FVZ-T13 is a quad micropower zero-drift precision operational amplifier manufactured by Renesas Electronics. It features rail-to-rail input and output capabilities, operating within a supply voltage range of 1.8 V to 6 V. Key electrical parameters include a gain-bandwidth product of 400 kHz, a slew rate of 200 mV/µs, and an input offset voltage of 6 µV. The device draws an operating supply current of 100 µA per channel and exhibits an input voltage noise density of 65 nV/√Hz. It is housed in a TSSOP-14 package.

Feature Summary

• Zero-drift architecture ensures high precision with minimal offset voltage drift over temperature.
• Rail-to-rail input and output stages maximize dynamic signal range in low-voltage applications.
• Micropower consumption design supports battery-operated systems with low quiescent current.

Applications

• Precision sensor signal conditioning
• Data acquisition systems
• Portable medical instrumentation

Procurement Notes

Verify the specific suffix 'T13' indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure compatibility with design specifications. Check for moisture sensitivity levels and recommended reflow profiles during assembly planning.

Selection Notes

Select this component for applications requiring low power consumption alongside high DC accuracy. The quad configuration reduces board space compared to single-channel alternatives. Ensure the required bandwidth does not exceed 400 kHz to maintain stability and performance characteristics defined in the datasheet.

Part Context

This part belongs to the ISL284xx series of zero-drift amplifiers from Renesas. It shares architectural similarities with other members like the ISL28430 but differs in channel count and specific electrical optimizations. The series is designed for general-purpose precision analog tasks where low power and high accuracy are critical constraints.
