ISL28194EVAL1Z, ISL28195EVAL1Z Evaluation

Board User’s Guide

Introduction

The ISL28194EVAL1Z, ISL28195EVAL1Z evaluation

board is a design platform containing all the circuitry

needed to characterize critical performance parameters

of the ISL28194 and ISL28195 operational amplifiers,

using a variety of user defined test circuits.

The ISL28194 and ISL28195 micro-power operational

amplifiers feature ultra-low power consumption,

rail-to-rail input and output drive capability, and are

designed to operate with two 1.5V Alkaline batteries.

Evaluation Board Key Features

The ISL28194EVAL1Z, ISL28195EVAL1Z is designed to

enable the IC to operate from a single supply, +1.8VDC

to +5.5VDC or from split supplies, ±0.9VDC to ±2.75V.

The board is configured for a single op amp connected for

differential input with a closed loop gain of 10. It also

contains a single external reference voltage (VREF) pin

and provisions for a user-selectable voltage divider (filter

are included).

Power Supplies

External power connections are made through the V+, V-

and Ground connections on the evaluation board. For

single supply operation, the V- and Ground pins are tied

together to the power supply negative terminal. For split
