ISL28408FBZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28408FBZ-T7A is a quad, low-power operational amplifier manufactured by Renesas Electronics. It features a rail-to-rail output stage and operates from a single supply voltage ranging from 2.5V to 16V. The device offers a gain-bandwidth product of 3MHz and a slew rate of 2V/µs. It includes internal frequency compensation for stability. The input common-mode voltage range extends to the negative rail, while the output swings within approximately 50mV of either supply rail. Quiescent current per amplifier is typically 350µA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix T7A indicates tape and reel packaging when ordering. Confirm the FBZ designation corresponds to the RoHS-compliant lead-free package variant. Ensure the operating temperature range matches your environmental requirements. Cross-reference the datasheet revision date to ensure compatibility with latest electrical specifications. Validate pinout assignments against your PCB layout design before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple low-power amplifiers are required in a compact form factor. Consider the 3MHz bandwidth for applications requiring moderate signal processing speeds. Evaluate the quiescent current against total system power budgets. Verify that the rail-to-rail output meets the load requirements of downstream stages. Compare input offset voltage specifications if high precision is necessary for the application.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL284xx family of quad operational amplifiers. It shares architectural similarities with other members like the ISL28409 but differs in specific electrical characteristics such as bandwidth and noise. The family is designed for general-purpose analog signal conditioning tasks. It complements dual-channel variants like the ISL282xx for designs requiring fewer channels.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include the ISL28408IBZ and ISL28408IBZ-T7A, which share identical pinouts and electrical specifications. Verify package type compatibility during replacement. Check for any minor variations in offset voltage or bias current if strict matching is required. Ensure the replacement part maintains the same RoHS compliance status.
