Ultra-Low Offset/Drift, Low-Noise,  
Precision SOT23 Amplifiers  
8/MAX4239  
General Description  
Features  
The MAX4238/MAX4239 are low-noise, low-drift, ultra-  
high precision amplifiers that offer near-zero DC offset  
and drift through the use of patented autocorrelating  
zeroing techniques. This method constantly measures  
and compensates the input offset, eliminating drift over  
time and temperature and the effect of 1/f noise. Both  
devices feature rail-to-rail outputs, operate from a single  
2.7V to 5.5V supply, and consume only 600µA. An active-  
low shutdown mode decreases supply current to 0.1µA.  
o Ultra-Low, 0.1µV Offset Voltage
