MAX4242
Single/Dual/Quad, +1.8V/10µA, SOT23, Beyond-the-Rails Op Amps
General 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 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
100kΩload. 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
