    AD797 Data Sheet
    0.9 nV/√Hz typical (1.2 nV/√Hz maximum) input voltage
    noise at 1 kHz
    50 nV p-p input voltage noise, 0.1 Hz to 10 Hz
    Low distortion
    -120 dB total harmonic distortion at 20 kHz
    Excellent ac characteristics
    800 ns settling time to 16 bits (10 V step)
    110 MHz gain bandwidth (G = 1000)
    8 MHz bandwidth (G = 10)
    280 kHz full power bandwidth at 20 V p-p
    20 V/μs slew rate
    Excellent dc precision
    80 μV maximum input offset voltage
    1.0 μV/°C VOS drift
    Specified for ±5 V and ±15 V power supplies
    High output drive current of 50 mA The AD797 is a very low noise, low distortion operational amplifier
    ideal for use as a preamplifier. The low noise of 0.9 nV/√Hz and
    low total harmonic distortion of -120 dB in audio bandwidths
    give the AD797 the wide dynamic range necessary for preamps ...
