OPAx325 Precision Operational Amplifier

Texas Instruments OPAx325 Precision Operational Amplifier is optimized for very low noise and wide bandwidth when operating on a low quiescent current of only 650µA. The OPAx325 features a linear input stage with zero crossover distortion. This op amp delivers an excellent common-mode rejection ratio (CMRR) of typically 114dB over the entire input range. The input common-mode range extends 100mV beyond the negative and positive supply rails. The output voltage typically swings within 10mV of the rails. The zero crossover distortion, combined with wide bandwidth, high slew rate, and low noise, makes this device a good SAR ADC input driver amplifier. The low offset and 0.2pA input bias current makes this device ideal for a wide range of precision applications with high-impedance sensors. The device features interfacing to high-impedance sensors on the input and can drive ADC inputs with minimal distortion. This feature makes the Texas Instruments OPAx325 suitable for various data acquisition and process control applications.
