ISL28166FHZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28166FHZ-T7 is a single-channel micropower precision operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.4V to 5V or dual supplies of ±1.2V to ±2.5V. The device incorporates an Input Range Enhancement Circuit (IREC) allowing input signals to exceed the positive supply rail while maintaining common-mode rejection ratio performance. Key electrical specifications include a typical supply current of 39µA, a maximum input bias current of 5nA, and a gain-bandwidth product of 250kHz at unity gain. The component is housed in a 6-lead SOT-23 package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features an Input Range Enhancement Circuit enabling input voltages to swing above the positive supply rail while maintaining CMRR performance.
• Provides rail-to-rail input and output operation with bipolar inputs extending to the negative rail and CMOS outputs swinging near both supply rails.
• Includes an enable pin that allows the device to be disabled for low-power standby modes, facilitating multiplexer configurations.

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 the specific ordering suffix T7 corresponds to the reel packaging specification as detailed in technical brief TB347. Confirm the package type matches the required footprint, as this part number specifies the 6-lead SOT-23 configuration. Ensure compatibility with RoHS compliance requirements and lead-free soldering profiles during assembly processes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low quiescent current is critical alongside precision signal conditioning. The IREC feature distinguishes it from standard RRIO amplifiers by supporting overvoltage input conditions relative to the positive rail. Consider the enable pin functionality if system power management requires channel disabling. Verify thermal dissipation calculations against the SOT-23 package thermal resistance limits under expected load conditions.
