ISL28266FBZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28266FBZ-T7 is a dual micropower precision operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output (RRIO) capabilities with an Input Range Enhancement Circuit (IREC). The device operates on a single supply voltage ranging from 2.4V to 5V or dual supplies of ±1.2V to ±2.5V. Key electrical specifications include a typical supply current of 78µA, a gain bandwidth product of 250kHz, and a maximum input bias current of 5nA. The input common-mode range extends beyond the positive supply rail, allowing signals to swing up to 0.5V above a 5.0V supply.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features an Input Range Enhancement Circuit (IREC) that maintains Common-Mode Rejection Ratio (CMRR) performance for input voltages exceeding the positive supply rail.
• Provides rail-to-rail input and output operation, enabling signal swings within millivolts of both supply rails.
• Delivers low-frequency noise performance comparable to devices with significantly higher supply currents, with a 1/f corner at 1kHz.
• Operates efficiently from single lithium cells or Ni-Cd batteries with minimal power consumption.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered systems
• Solar-powered systems
• 4mA to 20mA current loops
• Handheld consumer products
• Medical devices

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and Pb-free status as specified in the datasheet. Ensure proper electrostatic discharge handling procedures are followed during storage and assembly. Check for moisture sensitivity level requirements prior to soldering operations.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption alongside high precision. The dual-channel configuration is suitable for space-constrained designs needing two independent amplifiers. Consider the IREC feature if input signals may exceed the positive supply voltage. Evaluate thermal dissipation requirements based on load conditions and ambient temperature ranges.

Instrumentation, Op Amps, Buffer Amps Part Context

The ISL28266 belongs to the ISL28x66 family of micropower RRIO op amps, which also includes the single-channel ISL28166. Manufactured originally by Intersil Americas Inc., the product line was acquired by Renesas Electronics Corporation. The FBZ suffix indicates an 8-lead SOIC package variant, while the T7 suffix denotes tape and reel packaging.
