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 ampli-

fiers 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 combina-

tion of ultra-low-voltage operation, beyond-the-rails

inputs, rail-to-rail outputs, and ultra-low power con-

sumption 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 out-

puts typically swing to within 9mV of the rails with a

100kΩ load. Beyond-the-rails input and rail-to-rail out-

put 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.
