Ultralow Distortion, Ultralow Noise Op Amp Data Sheet AD797 . FEATURES GENERAL DESCRIPTION. Low noise The AD797 is a very low noise, low distortion operational amplifier nV/ Hz typical ( nV/ Hz maximum) input voltage ideal for use as a preamplifier. The low noise of nV/ Hz and noise at 1 kHz low total harmonic distortion of 120 dB in audio bandwidths 50 nV p-p input voltage noise, Hz to 10 Hz give the AD797 the wide dynamic range necessary for preamps Low distortion in microphones and mixing consoles. 120 dB total harmonic distortion at 20 kHz Furthermore, the AD797 has an excellent slew rate of 20 V/ s Excellent ac characteristics and a 110 MHz gain bandwidth, which makes it highly suitable 800 ns settling time to 16 bits (10 V step). for low frequency ultrasound applications.

Note, however, that this degrades the low noise performance of the device. ...
