Brief Description

The MAX4127ESA+T is an electronic component model in the IC Chips product category. It is a part of the MAX4122-MAX4129 family of operational amplifiers. These amplifiers offer wide bandwidth, excellent DC accuracy, and Rail-to-Rail operation at the inputs and outputs. The MAX4127ESA+T can operate from either a single supply (+2.7V to +6.5V) or dual supplies (±1.35V to ±3.25V) and has a common-mode voltage range that extends 250mV beyond VEE and VCC. It requires only 650µA per amplifier and is capable of driving 250Ω loads. This model has a gain bandwidth product of 5MHz and features a shutdown mode that reduces supply current to only 25µA per amplifier. It is available in a 5-pin SOT23-5 package.
