_____________________Selector Guide
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
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 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 outputs
typically swing to within 9mV of the rails with a 100kΩ
load. Beyond-the-rails input and rail-to-rail output char-
acteristics allow the full power-supply voltage to be
used for signal range. The combination of low input off-
set 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.
