AD797ARZ

AD797 is a very low noise, low distortion operational amplifier, ideal for use as a preamplifier. It 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 device 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 analysers. It is widely used in application such as professional audio preamplifiers, IR, CCD, and sonar imaging systems, spectrum analysers, ultrasound preamplifiers, seismic detectors, Σ-Δ ADC/DAC buffers etc.
