ISL28114FEZ-T7A

Instrumentation, Op Amps, Buffer Amps Overview

The ISL28114FEZ-T7A is a single-channel, micropower operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities, making it suitable for low-voltage applications. Key electrical specifications include a gain-bandwidth product of 5 MHz and a slew rate of 2.5 V/us. The device operates with an input offset voltage of 4 mV and an input bias current of 20 pA. It supports a supply voltage range from 1.8 V to 5.5 V while consuming only 360 uA of operating current per channel. The output can source up to 31 mA, and the common-mode rejection ratio is 72 dB. Input voltage noise density is specified at 40 nV/sqrt Hz, with input noise current density at 8 fA. The component is housed in a SC-70-5 package and is designed for surface mount installation.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix T7A indicates tape and reel packaging when ordering. Confirm the FEZ designation corresponds to the SC-70-5 package variant. Check current lifecycle status as discontinuation notices may apply to older Intersil-branded parts. Ensure compatibility with automated pick-and-place equipment due to the small outline package. Validate RoHS compliance documentation for final assembly requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low quiescent current is critical alongside moderate bandwidth requirements. Compare against the ISL28113 series if lower power consumption is prioritized over speed. Consider the ISL28114FHZ variant if a SOT-23-5 package is preferred for board space constraints. Evaluate thermal dissipation needs given the small package size and potential load currents.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the ISL2811x family of micropower operational amplifiers originally developed by Intersil and now produced by Renesas. The family includes single, dual, and quad configurations with varying bandwidth options. These amplifiers are designed for general-purpose applications requiring high precision in low-power environments. The FEZ suffix specifically denotes the SC-70-5 surface-mount package option within this product line.
