MAX4240MAX4244 19-1343 Rev 3 9/06 Single/Dual/Quad, +1.8V/10A, SOT23, Beyond-the-Rails Op Amps General Description Features The MAX4240MAX4244 family of micropower op amps Ultra-Low-Voltage Operation: operate from a single +1.8V to +5.5V supply or dual Guaranteed Down to +1.8V 0.9V to 2.75V supplies and have Beyond-the-Rails Typical Operation to +1.5V inputs and rail-to-rail output capabilities. These ampli- Ultra-Low Power Consumption: fiers provide a 90kHz gain-bandwidth product while using only 10A of supply current per amplifier. The 10A Supply Current per Amplifier MAX4241/MAX4243 have a low-power shutdown mode 1A Shutdown Mode (MAX4241/MAX4243) that reduces supply current to less than 1A and forces Up to 200,000 Hours Operation from Two AA the output into a high-impedance state. Although the Alkaline Cells minimum operating voltage is specified at +1.8V, these Beyond-the-Rails Input Common-Mode Range devices typically operate down to +1.5V. The combina- tion of ultra-low-voltage operation, beyond-the-rails Outputs Swing Rail-to-Rail inputs, rail-to-rail outputs, and ultra-low power con- No Phase Reversal for Overdriven Inputs sumption makes these devices ideal for any portable/ two-cell battery-powered system. 200V Input Offset Voltage These amplifiers have an input common-mode range Unity-Gain Stable for Capacitive Loads up to 200pF that extends 200mV beyond each rail, and their out- 90kHz Gain-Bandwidth Product puts typically swing to within 9mV of the rails with a 100k load. Beyond-the-rails input and rail-to-rail out- Available in Space-Saving 5-Pin SOT23 and put characteristics allow the full power-supply voltage 8-Pin MAX Packages to be used for signal range. The combination of low input offset voltage, low input bias current, and high Ordering Information open-loop gain makes them suitable for low-power/low- PIN- TOP voltage precision applications.
