ISL28214FUZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28214FUZ-T7 is a dual-channel, general-purpose, micropower operational amplifier manufactured by Renesas Electronics. It features rail-to-rail input and output (RRIO) capabilities, supporting a wide supply voltage range from 1.8V to 5.5V. Key electrical parameters include a gain-bandwidth product of 5 MHz, a slew rate of 2.5 V/µs, and an input offset voltage of 4 mV maximum. The device operates with a quiescent current of 720 µA per channel and offers low input bias current of 20 pA. It is housed in an MSOP-8 surface-mount package and functions reliably within an extended temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm lot traceability and humidity sensitivity handling requirements upon receipt. Ensure packaging integrity matches reel or cut-tape specifications. Cross-reference datasheet revisions to confirm parameter consistency. Validate that the specific suffix corresponds to the required tape-and-reel configuration for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel precision is required alongside low power consumption in single-supply systems. The RRIO feature simplifies interface design for sensors operating near ground or supply rails. Compare against the ISL28213 variant if lower bandwidth and reduced quiescent current are prioritized over speed. Ensure the MSOP-8 footprint aligns with existing PCB layout constraints. Verify thermal management needs given the small package size and ambient operating temperatures.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x14 series of micropower operational amplifiers from Renesas. It serves as the dual-channel counterpart to the single-channel ISL28114. The series is designed for general-purpose analog signal conditioning tasks requiring high accuracy and low power. The T7 suffix indicates tape-and-reel packaging suitable for high-volume automated manufacturing environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component is listed as end-of-life with discontinuation notifications present. Designers should evaluate alternative dual-channel RRIO op-amps from other manufacturers or consider redesigning with single-channel equivalents if pin compatibility allows.
