MAX4040MAX4044 19-1377 Rev 1 9/05 Single/Dual/Quad, Low-Cost, SOT23, Micropower Rail-to-Rail I/O Op Amps General Description Features The MAX4040MAX4044 family of micropower op amps Single-Supply Operation Down to +2.4V operates from a single +2.4V to +5.5V supply or dual Ultra-Low Power Consumption: 1.2V to 2.75V supplies and have rail-to-rail input and 10A Supply Current per Amplifier output capabilities. These amplifiers provide a 90kHz gain-bandwidth product while using only 10A of supply 1A 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 Outputs Swing Rail-to-Rail to less than 1A and forces the output into a high-imped- 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- 200V Input Offset Voltage sumption makes these devices ideal for any portable/battery-powered system. Unity-Gain Stable for Capacitive Loads up to 200pF These amplifiers have outputs that typically swing to 90kHz Gain-Bandwidth Product within 10mV of the rails with a 100k load. Rail-to-rail 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 MAX 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.
