MAX4321EUK+T
Low-Cost, Low-Voltage, Rail-to-Rail, Input/Output, SOT23 5MHz Op Amp
General Description
The MAX4321 operational amplifier (op amp) combines
a 5MHz gain-bandwidth product and excellent DC
accuracy with Rail-to-Rail®operation at both the inputs
and the output. This device requires only 650µA and
operates from either a single +2.4V to +6.5V supply or
dual ±1.2V to ±3.25V supplies, although the MAX4321
typically operates down to +1.8V (±0.9V). The
MAX4321 remains unity-gain stable with capacitive
loads up to 500pF and is capable of driving 250Ωloads
to within 200mV of either rail.
With rail-to-rail input common-mode range and output
swing, the MAX4321 is ideal for low-voltage, single-sup-
ply applications. In addition, low ±1.2mV input offset volt-
age and high 2V/µs slew rate make this device ideal for
signal-conditioning stages for precision, low-voltage data-
acquisition systems. The MAX4321 comes in a space-
saving 5-pin SOT23 package and is guaranteed over the
extended (-40°C to +85°C) temperature range.
The MAX4321 is a low-voltage, pin-for-pin compatible
upgrade for the LMC7101 that offers five-times higher
bandwidth, two-times faster slew rate, and about half the
input voltage noise density.
