DescriptionThe MAX4040MAX4044 family of micropower op amps operates from a single +2.4V to +5.5V supply or dual ±1.2V to ±2.75V supplies and have Rail-to-Rail® inputand out pabilities.These amplifiers provide a 90kHz gain-bandwidth product while using only 10µA of supply currenamplifiTheMAX4041/MAX4043haveaowpowershutdownmodethatreducessupplycurrent to less than 1µA and forces the output into a high-impedance state. The combination of low-voltage operation, rail-to-rail inputs and outputs, and ultra-lowpowerconsumption makes these MAX4040 ideal for any portable/battery-powered system.
These amplifiers MAX4040 have outputs that typically swing towithin 10mV of the rails with a 100kΩload. Rail-to-rail input and output characteristics allow the full power-supply voltage to be used for signal range. The combi- nation of 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 SOT23 package. All specifications are guaranteed over the -40°C to +85°C extended temperature range.
