MAX44250/MAX44251/MAX44252
20V, Ultra-Precision, Low-Noise Op Amps
General Description
The MAX44250/MAX44251/MAX44252 are 20V, ultra-
precision, low-noise, low-drift amplifiers that offer near-
zero DC offset and drift through the use of patented auto-
correlating zeroing techniques. This method constantly
measures and compensates the input offset, eliminating
drift over time and temperature and the effect of 1/f noise.
These single, dual, and quad devices feature rail-to-rail
outputs, operate from a single 2.7V to 20V supply or dual
±1.35V to ±10V supplies and consume only 1.15mA
per channel, while providing 5.9nV/
√Hz input-referred
voltage noise. The ICs are unity-gain stable with a gain-
bandwidth product of 10MHz.
With excellent specifications such as offset voltage of
6V (max), drift of 19nV/°C (max), and 123nVP-P noise in
0.1Hz to 10Hz, the ICs are ideally suited for applications
requiring ultra-low noise and DC precision such as inter-
facing with pressure sensors, strain gauges, precision
weight scales, and medical instrumentation.
The ICs are available in 5-pin SOT23, 8-pin SOT23,
8-pin MAXM, and 14-pin SO packages and are rated
over the -40°C to +125°C temperature range.
