General Description
The MAX44244/MAX44245/MAX44248 family of parts
provide ultra-precision, low-noise, zero-drift single/quad/
dual operational amplifiers featuring very low-power
operation with a wide supply range. The devices incor-
porate a patented auto-zero circuit that constantly mea-
sures and compensates the input offset to eliminate drift
over time and temperature as well as the effect of 1/f
noise. These devices also feature integrated EMI filters
to reduce high-frequency signal demodulation on the
output. The op amps operate from either a single 2.7V to
36V supply or dual ±1.35V to ±18V supply. The devices
are unity-gain stable with a 1MHz gain-bandwidth prod-
uct and a low 90µA supply current per amplifier.
The low offset and noise specifications and high supply
range make the devices ideal for sensor interfaces and
transmitters.
The devices are available in FMAXM, SO, SOT23, and
TSSOP packages and are specified over the -40NC to
+125NC automotive operating temperature range.
