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 …
