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 10A of supply current per amplifier. The
MAX4241/MAX4243 have a low-power shutdown mode
that reduces supply current to less than 1A 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
100k
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.
