Maxim Integrated MAX4163 Micropower Op Amps combine an exceptional bandwidth to power consumption ratio with true rail-to-rail inputs and outputs. MAX4163 op amps consume a mere 25µA quiescent current per amplifier, achieve 200kHz gain-bandwidth product, and are unity-gain stable while driving any capacitive load. The Maxim Integrated MAX4163 operates from either a single supply (2.5V to 10V) or dual supplies (±1.25V to ±5V), with an input common-mode voltage range extending 250mV beyond either supply rail. These Maxim Integrated devices use a proprietary architecture to achieve a very high input common-mode rejection ratio without the midswing nonlinearities present in other rail-to-rail op amps. This architecture also maintains high open-loop gain and output swing, while driving substantial loads. MAX4163 Micropower Op Amps are ideal for use in a variety of applications, including battery-powered devices, medical instruments, pH probes, portable equipment, cell phones, and more.
