19-1612; Rev 0; 3/00 Ultra-Small, +1.8V, µPower, Rail-to-Rail I/O Op Amps 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.
