MAX4241ESA
19-1343; Rev 3; 9/06 Single/Dual/Quad, +1.8V/10µA, SOT23, Beyond-the-Rails Op Amps Features The MAX4240–MAX4244 family of micropower op amps operate from a single +1.8V to +5.5V supply or dual ±0.9V to ±2.75V supplies and have Beyond-the-Rails™ inputs and rail-to-rail output capabilities. These amplifiers provide a 90kHz gain-bandwidth product while using only 10µA of supply current per amplifier. The MAX4241/MAX4243 have a low-power shutdown mode that reduces supply current to less than 1µA and forces the output into a high-impedance state. Although the minimum operating voltage is specified at +1.8V, these devices typically operate down to +1.5V. The combination of ultra-low-voltage operation, beyond-the-rails inputs, rail-to-rail outputs, and ultra-low power consumption makes these devices ideal for any portable/ two-cell battery-powered system. ♦ Ultra-Low-Voltage Operation: Guaranteed Down to +1.8V Typical Operation to +1.5V These amplifiers have an input common-mode range that extends 200mV beyond each rail, and their outputs typically swing to within 9mV of the rails with a 100kΩ load. Beyond-the-rails input and rail-to-rail output characteristics allow the full power-supply voltage to be used for signal range. The combination of low input offset voltage, low input bias current, and high open-loop gain makes them suitable for low-power/lowvoltage precision applications. The MAX4240 is offered in a space-saving 5-pin SOT23 package. All specifications are guaranteed over the -40°C to +85°C extended temperature range. ♦ Unity-Gain Stable for Capacitive Loads up to 200pF Applications Two-Cell BatteryPowered Systems Portable/Battery-Powered Electronic Equipment Digital Scales Strain Gauges Sensor Amplifiers Cellular Phones Notebook Computers PDAs ♦ Ultra-Low Power Consumption: 10µA Supply Current per Amplifier 1µA Shutdown Mode (MAX4241/MAX4243) Up to 200,000 Hours Operation from Two AA Alkaline Cells ♦ Beyond-the-Rails Input Common-Mode Range ♦ Outputs Swing Rail-to-Rail ♦ No Phase Reversal for Overdriven Inputs ♦ 200µV Input Offset Voltage ♦ 90kHz Gain-Bandwidth Product ♦ Available in Space-Saving 5-Pin SOT23 and 8-Pin µMAX® Packages Ordering Information PART TEMP RANGE PINPACKAGE TOP MARK MAX4240EUK-T -40°C to +85°C 5 SOT23-5 ACCS MAX4241EUA -40°C to +85°C 8 µMAX — MAX4241ESA -40°C to +85°C 8 SO — MAX4242EUA -40°C to +85°C 8 µMAX — MAX4242ESA -40°C to +85°C 8 SO — MAX4243EUB -40°C to +85°C 10 µMAX — MAX4243ESD -40°C to +85°C 14 SO — MAX4244ESD -40°C to +85°C 14 SO — Pin Configurations Selector Guide PART NO.
