Details
General DescriptionThe 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 asingle 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 Voltage2.0µV (max) at +25°C2.5µV (max) at -40°C to +85°C3.5µV (max) at -40°C to +125°C♦Low 10nV/°C Drift♦Specified over the -40°C to +125°C Automotive Temperature Range♦Low Noise: 1.5µVP-Pfrom DC to 10Hz♦150dB AVOL, 140dB PSRR, 140dB CMRR♦High Gain-Bandwidth Product1MHz (MAX4238)6.5MHz (MAX4239)♦0.1µA Shutdown Mode♦Rail-to-Rail Output (RL= 1kΩ)♦Low 600µA Supply Current♦Ground-Sensing Input♦Single 2.7V to 5.5V Supply Voltage Range♦Available in a Space-Saving 6-Pin SOT23 Package
