ISL28214FBZ

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28214FBZ is a dual-channel, micropower operational amplifier manufactured by Renesas Electronics. It features rail-to-rail input and output (RRIO) capabilities with a gain-bandwidth product of 5 MHz and a slew rate of 2.5 V/µs. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V, consuming 720 µA of quiescent current. Key electrical specifications include an input offset voltage of 4 mV, input bias current of 20 pA, and an input voltage noise density of 40 nV/√Hz. It provides a common-mode rejection ratio of 72 dB and can deliver up to 31 mA per channel. The component is housed in an SOIC-8 surface-mount package and supports an extended operating temperature range from -40 °C to +125 °C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FBZ' against the manufacturer's latest documentation to confirm pinout compatibility and RoHS status. Confirm availability as the component may be subject to end-of-life notices or obsolescence warnings. Ensure the SOIC-8 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low power consumption is critical alongside the need for full signal swing near the supply rails. The 5 MHz bandwidth suits general-purpose applications requiring moderate speed. Consider the 4 mV offset voltage for precision requirements; higher precision alternatives within the same family may be necessary if stricter accuracy is needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28214 series of micropower amplifiers. It shares functional similarities with other members of the family but differs in channel count and specific packaging options such as MSOP8 and SOT23-8. The FBZ suffix typically denotes the SOIC-8 tube packaging variant.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct substitutes within the ISL2821x series that offer identical pinouts and electrical characteristics. Verify if newer generation parts from Renesas provide improved performance metrics while maintaining backward compatibility.
