MAX4042:Single/Dual/Quad, Low-Cost, SOT23, Micropower Rail-to-Rail I/O Op Amps

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-impedance state. The combination of low-voltage operation, rail-to-rail inputs and outputs, and ultra-low power consumption makes these devices ideal for any portable/battery-powered system. These amplifiers have outputs that typically swing to within 10mV of the rails with a 100kΩ load. Rail-to-rail input and output characteristics allow the full power-supply voltage to be used for signal range. The combination 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.
