36V, Low-Noise, Precision,
Single/Quad/Dual Op Amps
General Description
The MAX44241/MAX44243/MAX44246 are 36V, ultra-
precision, low-noise, low-drift, single/quad/dual opera-
tional amplifiers that offer near-zero DC offset and drift
through the use of patented chopper stabilized and
auto-zeroing techniques. This method constantly mea-
sures and compensates the input offset, eliminating drift
over time and temperature and the effect of 1/f noise.
These single/quad/dual devices feature rail-to-rail out-
puts, operate from a single 2.7V to 36V supply or dual
±1.35V to ±18V supplies, and consume only 0.42mA per
channel, with only 9nV/√Hz input-referred voltage noise.
The ICs are unity-gain stable with a gain-bandwidth
product of 5MHz. With excellent specifications such as
offset voltage of 5FV (max), drift of 20nV/NC (max), and
117nV_P-P noise in 0.1Hz to 10Hz, these ICs are ideally
suited for applications requiring ultra-low noise, and DC
precision such as interfacing with pressure sensors,
strain gauges, precision weight scales, and medical
instrumentation.
The ICs are available in 8-pin FMAXM or SO packages
and are rated over the -40NC to +125NC temperature
range.
