Description

The MAX4126ESA+T is an instrumentation op-amp belonging to the MAX4122-MAX4129 family. It features excellent DC accuracy and wide bandwidth along with rail-to-rail operation at the inputs and outputs. It operates from a single supply voltage of +2.7V to +6.5V or dual supplies of ±1.35V to ±3.25V. These devices require 650μA per amplifier and are capable of driving 250Ω loads. Its gain-bandwidth product is 5MHz. It comes in a 5-pin SOT23-5 package, which saves space in the design layout.
