ISL28414FBZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28414FBZ-T7 is a quad-channel operational amplifier from the Renesas ISL28414 series, designed for general-purpose applications. It features rail-to-rail input and output capabilities, allowing operation across the full supply voltage range. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V. Key electrical specifications include a gain-bandwidth product of 5 MHz, a slew rate of 2.5 V/us, an input offset voltage of 4 mV, and an input bias current of 20 pA. The quiescent current per channel is 600 uA, with a total operating supply current of 2.4 mA. Input voltage noise density is 40 nV/sqrt Hz, and input current noise density is 8 fA/sqrt Hz. The component is housed in a TSSOP-14 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 'T7' indicates tape and reel packaging when sourcing. Confirm the 'FBZ' variant matches the required pinout and thermal characteristics against the official datasheet. Check for end-of-life status as older Intersil/Renesas components may have limited availability or require obsolescence management planning.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple low-power, general-purpose amplifiers are needed in a compact form factor. The rail-to-rail I/O makes it suitable for single-supply designs where signal swing must approach the rails. Ensure the 5 MHz bandwidth meets the application's frequency requirements and that the 4 mV offset voltage is acceptable for the required precision level.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28414 family of micropower operational amplifiers. It shares core electrical characteristics with other variants like the ISL28414FVZ but differs in package type (SOIC-14 vs TSSOP-14) and potentially thermal performance. The series is known for combining low power with good AC performance.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements include ISL28414FVZ-T7 (same electrical specs, different TSSOP-14 package). Verify pin compatibility before substitution. Other quad op-amps with similar GBP and rail-to-rail I/O may be considered if package differences are acceptable.
