EVALUATION KIT AVAILABLE
36V, Low-Noise, Precision,
Single/Quad/Dual Op Amps
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 available in 8-pin FMAXM or SO packages
and are rated over the -40NC to +125NC temperature
