描述
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.
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/low-voltage 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.
