Single/Dual/Quad, Low -Cost, SOT23 , Micropow er Rail-to-Rail I /O Op Amps


General Description

The MAX4040–MAX4044 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 input and output capabilities. These amplifiers provide a 90kHz gain-bandwidth product while using only 10µA of supply current per amplifier. The MAX4041/MAX4043 have a low-power shutdown mode that reduces supply current to less than 1µA and forces the output into a high-imped- ance state. The combination of low-voltage operation, rail-to-rail inputs and outputs, and ultra-low power con- sump tion makes these d evic es id eal for any portable/battery-powered system.

These amplifiers have outputs that typically swing to within 10mV of the rails with a 100k load. 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.
