Description

General Description
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.
Features
♦Ultra-Low, 0.1µV Offset Voltage
2.0µV (max) at +25°C
2.5µV (max) at -40°C to +85°C
3.5µV (max) at -40°C to +125°C
♦Low 10nV/°C Drift
♦Specified over the -40°C to +125°C Automotive Temperature Range
