产品概述

The MAX4040–MAX4044 family of micropower op ampsoperates from a single +2.4V to +5.5V supply or dual±1.2V to ±2.75V supplies and have rail-to-rail input andoutput capabilities. These amplifiers provide a 90kHzgain-bandwidth product while using only 10µA of supplycurrent per amplifier. The MAX4041/MAX4043 have alow-power shutdown mode that reduces supply currentto less than 1µA and forces the output into a high-impedancestate. The combination of low-voltage operation,rail-to-rail inputs and outputs, and ultra-low power consumptionmakes these devices ideal for anyportable/battery-powered system.

These amplifiers have outputs that typically swing towithin 10mV of the rails with a 100kΩ load. Rail-to-railinput and output characteristics allow the full power-supplyvoltage to be used for signal range. The combinationof low input offset voltage, low input bias current,and high open-loop gain makes them suitable for low-power/low-voltage precision applications.

The MAX4040 is offered in a space-saving 5-pin SOT23package. All specifications are guaranteed over the-40°C to +85°C extended temperature range.
