19-1195; Rev 3; 1/10 UCSP, Micropower, Single-Supply, 10V,Rail-to-Rail I/O Op AmpsMAX4162/MAX4163/MAX4164General DescriptionFeatures The MAX4162/MAX4163/MAX4164 are single/dual/quad, o UCSP Package (MAX4163) micropower operational amplifiers that combine an o 1.0pA Typical Input Bias Current exceptional bandwidth to power consumption ratio with true rail-to-rail inputs and outputs. They consume a o Single-Supply Operation from 2.5V to 10V mere 25µA quiescent current per amplifier, yet achieve o Input Common-Mode Voltage Range Extends 200kHz gain-bandwidth product and are unity-gain 250mV Beyond Either Supply Rail stable while driving any capacitive load. The MAX4162/ o Rail-to-Rail Output Swing MAX4163/MAX4164 operate from either a single supply (2.5V to 10V) or dual supplies (±1.25V to ±5V), with an o 200kHz Gain-Bandwidth Product input common-mode voltage range that extends 250mV o 25µA Quiescent Current per Amplifier beyond either supply rail. These amplifiers use a propri- o Excellent CMRR, PSRR, and Gain Linearity etary architecture to achieve a very high input common- mode rejection ratio without the midswing nonlinearities o No Phase Reversal for Overdriven Inputs present in other rail-to-rail op amps. This architecture o Unity-Gain Stable also maintains high open-loop gain and output swing o Stable with Any Capacitive Load while driving substantial loads. o Internally Short-Circuit Protected to Either Rail The combination of excellent bandwidth/power perfor- mance, single-supply operation, and miniature footprint Ordering Information makes these op amps ideal for portable equipment and other low-power, single-supply applications.
