ISL28156FBZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28156FBZ is a micropower precision operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7V to 36V or dual supplies of ±1.35V to ±18V. The device draws a typical quiescent current of 39µA per channel. Key electrical specifications include a maximum input offset voltage of 400µV, a gain-bandwidth product of 1MHz, and a slew rate of 0.3V/µs. Input bias current is typically 2pA at 25°C. It is housed in an 8-lead SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer source, as Intersil operations were acquired by Renesas Electronics. Confirm the specific datasheet revision matches the required electrical tolerances. Ensure the SOIC-8 package variant aligns with PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption is critical alongside precision requirements. The rail-to-rail I/O allows operation near supply rails, maximizing dynamic range in single-supply designs. Consider the 1MHz bandwidth limit for higher frequency applications where faster response times are needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL2815x family of micropower op amps. It shares architectural similarities with the ISL28157 (dual) and ISL28158 (quad) variants. The FBZ suffix indicates a lead-free, halogen-free RoHS-compliant package. It serves as a low-power alternative to standard precision amplifiers in portable electronics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same family include the ISL28157FBZ (dual channel) and ISL28158FBZ (quad channel). Cross-brand equivalents may require verification of pinout compatibility and electrical parameter matching.
