MAX4243
Description
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 90k Hz 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 bination of ultra-low-voltage operation, beyond-therails 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 mon-mode range that extends 200m V beyond each rail, and their outputs typically swing to within 9m V of the rails with a 100kΩ load.
