Benefits
• Maintain system calibration and
accuracy over time and temperature
with low-temperature coefficients
◦ Autozero technology reduces
voltage offset temperature
coefficient (TCV
OS
) to 20nV/˚C and
V
OS
to only 6µV (max)
• Improve system accuracy and
resolution with low-input voltage
noise
◦ Having no 1/f component ensures
low-distortion signal conditioning
below 0.1Hz with 5.9nV input-
voltage noise density
Improve Accuracy with Precision Over Time
and Precision Over Temperature from Ultra-
High-Precision Op Amps
MAX44251/MAX44252
*
The MAX44251/MAX44252 are 20V, ultra-precision, low-noise, low-drift ampliers
that oer near-zero DC oset and drift through the use of patented autocorrelating
zeroing techniques. This method constantly measures and compensates the input
oset, thereby eliminating drift over time and temperature, and the eect of 1/f noise.
