ISL28133FEZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28133FEZ-T7 is a single-channel, micro-power, rail-to-rail input/output operational amplifier from the ISL28x33A family. It features chopper-stabilized zero-drift architecture for high precision. The device operates on a single supply voltage ranging from 1.8V to 5.5V or dual supplies of ±0.9V to ±2.75V. Key electrical parameters include a maximum input offset voltage of 40µV and a maximum offset drift of 150nV/°C. It draws a typical quiescent current of 20µA per channel with a gain-bandwidth product of 400kHz.

• Chopper-stabilized zero-drift technology ensures low offset voltage and minimal drift over temperature variations.
• Rail-to-rail input and output capability maximizes dynamic range in low-voltage single-supply applications.
• Micro-power consumption design enables extended battery life in portable and handheld devices.

Instrumentation, Op Amps, Buffer Amps Applications

• Precision sensor signal conditioning
• Medical instrumentation such as infusion pumps
• Portable battery-powered test equipment

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FEZ' against the manufacturer's official datasheet to confirm the package type (SC-70-5) and tape-and-reel quantity. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the Renesas part number with Intersil legacy codes if integrating into existing designs. Confirm availability status directly with authorized distributors as supply levels may fluctuate.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low drift and high accuracy are required alongside minimal power consumption. It is suitable for applications where the input and output signals must swing close to the supply rails. Compare it against standard op-amps if noise performance at higher frequencies is critical, as chopper amplifiers may exhibit residual ripple. Consider the SC-70-5 package constraints for PCB layout space.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL28x33A series of precision CMOS operational amplifiers designed for compact spaces. It shares architectural similarities with the ISL28130 but offers enhanced drift characteristics. The series is optimized for single-supply operation and is commonly used in industrial and consumer electronics requiring high precision.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include ISL28133FHZ-T7 (different package). Verify pin compatibility before replacing with other chopper-stabilized amplifiers. Check datasheets for differences in input bias current and noise density.
