GENERAL DESCRIPTION

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 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/μs and

110 MHz gain bandwidth make it highly suitable for low

frequency ultrasound applications.

The AD797 is also useful in infrared (IR) and sonar imaging

applications, where the widest dynamic range is necessary. The

low distortion and 16-bit settling time of the AD797 make it

ideal for buffering the inputs to Σ-Δ ADCs or the outputs of

high resolution DACs, especially when the device is used in

critical applications such as seismic detection or in spectrum

analyzers. Key features such as a 50 mA output current drive

and the specified power supply voltage range of ±5 V to ±15 V

make the AD797 an excellent general-purpose amplifier.
