FEATURES
PIN CONFIGURATIONS Low noise: 80 nV p-p (0.1 Hz to 10 Hz), 3 nV/√Hz Low drift: 0.2 µV/°C High speed: 2.8 V/µs slew rate, 8 MHz gain bandwidth Low VOS: 10 µV CMRR: 126 dB at VCM of ±11 V High open-loop gain: 1.8 million Available in die form GENERAL DESCRIPTION
Low noise, en = 3.5 nV/√Hz, at 10 Hz, a low 1/f noise corner frequency of 2.7 Hz, and high gain (1.8 million), allow accurate high-gain amplification of low-level signals. A gain bandwidth product of 8 MHz and a 2.8 V/µs slew rate provide excellent dynamic accuracy in high speed, data-acquisition systems.
