Part Manufacturer: Maxim


Part Description: MAX4238 39 DS

Part Details:

19-2424; Rev 2; 5/06 Ultra-Low Offset/Drift, Low-Noise, Precision SOT23 Amplifiers MAX4238/MAX4239 General Description Features The MAX4238/MAX4239 are low-noise, low-drift, ultra- Ultra-Low, 0.1µV Offset Voltage high precision amplifiers that offer near-zero DC offset 2.0µV (max) at +25°C and drift through the use of patented autocorrelating 2.5µV (max) at -40°C to +85°C zeroing techniques. This method constantly measures 3.5µV (max) at -40°C to +125°C and compensates the input offset, eliminating drift overtime and temperature and the effect of 1/f noise. Both Low 10nV/oC Drift devices feature rail-to-rail outputs, operate from a single Specified over the -40oC to +125oC Automotive 2.7V to 5.5V supply, and consume only 600µA. An active-low shutdown mode decreases supply current to 0.1µA. Temperature Range The MAX4238 is unity-gain stable with a gain-band- Low Noise: 1.5µVP-P from DC to 10Hz width product of 1MHz, while the decompensated 150dB AVOL, 140dB PSRR, 140dB CMRR MAX4239 is stable with AV 10V/V and a GBWP of6.5MHz. The MAX4238/MAX4239 are available in 8-pin High Gain-Bandwidth Product narrow SO, 6-pin TDFN and SOT23 packages. 1MHz (MAX4238)6.5MHz (MAX4239) Applications 0.1µA Shutdown Mode Rail-to-Rail Output (RL = 1k) Thermocouples Low 600µA Supply Current Strain Gauges Ground-Sensing Input Electronic Scales Single 2.7V to 5.5V Supply Voltage Range Medical Instrumentation Instrumentation Amplifiers Available in a Space-Saving 6-Pin SOT23 and TDFN Packages Ordering Information Typical Application Circuit PIN- TOP PKG PART PACKAGE MARK CODE 5V MAX4238AUT-T 6 SOT23-6 AAZZ U6F-6 MAX4238ASA
