19-1377; Rev 1; 9/05 Single/Dual/Quad, Low-Cost, SOT23,Micropower Rail-to-Rail I/O Op AmpsMAX4040–MAX4044________________General Description____________________________Features The MAX4040–MAX4044 family of micropower op amps ♦ Single-Supply Operation Down to +2.4V 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 ♦ Ultra-Low Power Consumption: output capabilities. These amplifiers provide a 90kHz 10µA Supply Current per Amplifier gain-bandwidth product while using only 10µA of supply 1µA Shutdown Mode (MAX4041/MAX4043) current per amplifier. The MAX4041/MAX4043 have a ♦ Rail-to-Rail Input Common-Mode Range low-power shutdown mode that reduces supply current to less than 1µA and forces the output into a high-imped- ♦ Outputs Swing Rail-to-Rail ance state. The combination of low-voltage operation, ♦ No Phase Reversal for Overdriven Inputs rail-to-rail inputs and outputs, and ultra-low power con- sumption makes these devices ideal for any ♦ 200µV Input Offset Voltage portable/battery-powered system. ♦ Unity-Gain Stable for Capacitive Loads up to 200pF These amplifiers have outputs that typically swing to within 10mV of the rails with a 100kΩ load. Rail-to-rail ♦ 90kHz Gain-Bandwidth Product input and output characteristics allow the full power- ♦ Available in Space-Saving 5-Pin SOT23 and supply voltage to be used for signal range. The combi- 8-Pin µMAX® Packages nation of low input offset voltage, low input bias current, and high open-loop gain makes them suitable for low- power/low-voltage precision applications. Ordering Information The MAX4040 is offered in a space-saving 5-pin SOT23 package.
