MAX4294 General Description
The MAX4291/MAX4292/MAX4294 family of micropower operational amplifiers operates from a +1.8V to +5.5V single supply or ±0.9V to ±2.75V dual supplies and has Rail-to-Rail® input/output capabilities. These amplifiers provide a 500kHz gain-bandwidth product and 120dB open-loop voltage gain while using only 100µA of supply current per amplifier. The combination of low input offset voltage (±400µV) and high-open-loop gain makes them suitable for low power/low-voltage high-precision applications.
The MAX4291/MAX4292/MAX4294 have an input common-mode range that extends to each supply rail, and their outputs typically swing within 20mV of the rails with a 2kΩ load. Although the minimum operating voltage is specified at +1.8V, these devices typically operate down to +1.5V. The combination of ultra-low-voltage operation, rail-to-rail inputs/output, and low-power consumption makes these devices ideal for any portable/two-cell battery-powered system.
The single MAX4291 is offered in an ultra-small 5-pin SC70 package and the dual MAX4292 is offered in a space-saving 8-pin µMAX package.
