MAX4122EUK+T

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P16
General Description
The MAX4122–MAX4129 family of operational amplifiers
combines wide bandwidth and excellent DC accuracy with
Rail-to-Rail
®
operation at the inputs and outputs. These
devices require only 650µA per amplifier, and operate from
either a single supply (+2.7V to +6.5V) or dual supplies
(±1.35V to ±3.25V) with a common-mode voltage range
that extends 250mV beyond V
EE
and V
CC
. They are capa-
ble of driving 250Ω loads. The MAX4122/MAX4123/
MAX4126/MAX4127/MAX4129 have a 5MHz gain band-
width product, while the decompensated MAX4124/
MAX4125/MAX4128 (stable at closed-looped gains of
10 or greater) have a 25MHz gain bandwidth product. In
addition, the MAX4123/MAX4125/MAX4127 feature a
shutdown mode in which the outputs are placed in a
high-impedance state and the supply current is reduced
to only 25µA per amplifier.
With their rail-to-rail input common-mode range and
output swing, these amplifiers are ideal for low-voltage
single-supply operation. Although the minimum operat-
ing voltage is specified at 2.7V, the devices typically
operate down to 1.8V. In addition, low offset voltage
and high speed make them the ideal signal-condition-
ing stages for precision, low-voltage, data-acquisition
systems. The MAX4122 and MAX4124 come in the
space-saving 5-pin SOT23-5 package.
