EL8178BIWZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The EL8178BIWZ-T7 is a micropower single-supply rail-to-rail input-output precision operational amplifier manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.4V to 5.5V and features an enable pin that reduces supply current to 3µA in the disabled state, with a typical active current of 55µA. The device provides a gain-bandwidth product of 266kHz, a maximum offset voltage of 250µV, and a typical input bias current of 1pA. It supports ground sensing and can source or sink up to 26mA of load current.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output operation without performance degradation across the common-mode range
• Active low enable pin for power-sensitive applications reducing standby current significantly
• High-impedance PFET input stage ensuring smooth offset voltage behavior throughout the input range

Instrumentation, Op Amps, Buffer Amps Applications

• Battery- or solar-powered systems
• Thermocouple amplifiers
• pH probe amplifiers
• Photodiode pre-amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'BIWZ' against official manufacturer documentation, as standard listings typically reference FWZ or FSZ variants. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Ensure the package type matches the design constraints, as this part number implies a specific reel configuration distinct from bulk or tape options.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high precision with minimal power consumption under single-supply conditions. The rail-to-rail capability allows direct interfacing with sensors biased at ground. Consider the thermal resistance of the SOT-23 package when calculating junction temperatures under heavy loads or elevated ambient conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the EL8178 family of micropower precision amplifiers. It shares core electrical characteristics with other EL8178 variants but differs in packaging and shipping format. The series is designed for portable electronics where battery life and signal accuracy are critical constraints.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult Intersil technical support for confirmed substitute products. Standard equivalents include EL8178FWZ-T7 and EL8178FSZ, though package dimensions and lead counts differ between SOT-23 and SO-8 formats.
