Overview
The ISL28488FAZ is a quad micropower operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities, supporting single-supply operation from 3V to 40V. The device offers a gain-bandwidth product of 1.2 MHz and a slew rate of 450 mV/µs. Key electrical specifications include an input offset voltage of 25 µV, input bias current of 13 nA, and common-mode rejection ratio of 102 dB. Input voltage noise density is 15.8 nV/√Hz. Operating supply current is 270 µA per channel, with each channel capable of delivering 30 mA output current. It operates within a temperature range of -40°C to 125°C.
Feature Summary
- Quad configuration with rail-to-rail input and output for maximum dynamic range in single-supply applications
- Micropower consumption design suitable for battery-operated systems
- High precision performance with low offset voltage and high common-mode rejection
Applications
- Precision sensor signal conditioning
- Data acquisition systems
- Industrial process control instrumentation
Procurement Notes
Verify component authenticity through authorized distributors as the part is obsolete. Confirm package integrity and pin alignment against the QSOP-16 specification. Check manufacturing date codes for potential shelf-life limitations. Ensure storage conditions meet manufacturer guidelines to prevent degradation. Validate compatibility with existing circuit designs before integration.
Selection Notes
Consider the quad topology when multiple amplifier channels are required in a compact footprint. Evaluate power budget constraints given the micropower characteristics. Assess precision requirements against the specified offset voltage and drift parameters. Verify supply voltage ranges align with system rails. Compare thermal performance if operating near upper temperature limits.
Part Context
This component belongs to the ISL284xx series of precision operational amplifiers. It shares architectural similarities with other members like the ISL28408FBZ but differs in channel count and specific packaging. The series emphasizes low power and high accuracy for analog signal processing tasks.
Replacement Considerations
The ISL28488FAZ-T7 is a tape-and-reel variant of this component. Verify pinout and electrical specifications match exactly before substitution. Note that both parts are classified as obsolete by the manufacturer.
