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 0.9 nV/Hz typical (1.2 nV/Hz maximum) input voltage ideal for use as a preamplifier. The low noise of 0.9 nV/Hz and noise at 1 kHz low total harmonic distortion of -120 dB in audio bandwidths 50 nV p-p input voltage noise, 0.1 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. 110 MHz gain bandwidth (G = 1000) 8 MHz bandwidth (G = 10) The AD797 is also useful in infrared (IR) and sonar imaging 280 kHz full power bandwidth at 20 V p-p applications, where the widest dynamic range is necessary. The 20 V/s slew rate low distortion and 16-bit settling time of the AD797 make it Excellent dc precision ideal for buffering the inputs to - ADCs or the outputs of 80 V maximum input offset voltage high resolution DACs, especially when the device is used in 1.0 V/
