EL8186IWZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The EL8186IWZ-T7A is a micropower single-supply rail-to-rail input-output operational amplifier optimized for operation at 5V, functioning down to 2.4V. It features a supply current of 55µA, a typical offset voltage of 400µV, and an input bias current of 500pA. The device provides a gain-bandwidth product of 400kHz and a unity-gain bandwidth of 1MHz with a slew rate of 0.13V/µs. It operates from a single supply ranging from 2.4V to 5.5V, includes an active-low enable pin, and is housed in a 6-pin SOT-23 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm RoHS compliance and Pb-free status via official datasheets. Check for moisture sensitivity level (MSL) requirements before soldering. Ensure ordering suffixes match specific packaging configurations. Validate that the part number corresponds to the exact electrical specifications required for the design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring low power consumption alongside precision signal conditioning. The rail-to-rail input/output eliminates headroom issues in single-supply systems. Consider the enable pin functionality if system-wide power management or channel multiplexing is necessary. Verify that the 400kHz gain-bandwidth product meets the frequency response requirements of the application.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the EL8186 handle input offset voltage changes near the supply rails?

Unlike conventional rail-to-rail amplifiers that switch between differential pairs causing offset jumps, the EL8186 maintains smooth input offset voltage behavior throughout the entire common-mode input range.

What is the default state of the enable pin if left unconnected?

The enable pin has an internal pull-down resistor; if left open, it pulls to the negative rail, causing the device to be enabled by default.
