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.  
Specified for 5 V and 15 V power supplies  
High output drive current of 50 mA  
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.  
APPLICATIONS  
Professional audio preamplifiers  
IR, CCD, and sonar imaging systems  
Spectrum analyzers  
Ultrasound preamplifiers  
Seismic detectors  
Σ-Δ ADC/DAC buffers
