PRODUCT DE SCRIPT ION
T he AD797 is a very low noise, low distortion operational
amplifier ideal for use as a preamplifier. T he low noise of
0.9 nV/
√
Hz
and low total harmonic distortion of –120 dB at
audio bandwidths give the AD797 the wide dynamic range

necessary for preamps in microphones and mixing consoles.
Furthermore, the AD797’s excellent slew rate of 20 V/
μ
s and
110 MHz gain bandwidth make it highly suitable for low fre-
quency ultrasound applications.
T he AD797 is also useful in IR and Sonar Imaging applications
where the widest dynamic range is necessary. T he low distor-
tion and 16-bit settling time of the AD797 make it ideal for
buffering the inputs to
Σ
ADCs or the outputs of high resolu-
tion DACs especially when they are used in critical applications
such as seismic detection and spectrum analyzers. K ey features
such as a 50 mA output current drive and the specified power
supply voltage range of
±
5 to
±
15 volts make the AD797 an
excellent general purpose amplifier.
