TitleIC OPAMP GP 110MHZ 8SOIC
Description

ADI’s AD797 is a low distortion and low noise operation amplifier. The op amp with low harmonic distortion of -120 dB which is perfect for a wide dynamic range necessary for precision applications. The excellent slew rate of 20 V / µs and 110 MHz gain is needed for ultrasound applications, such as sonar and seismic uses. The device comes in either an 8-PDP or 8-SOIC package with a temperature range of -40°C to +85°C. The AD797 is ideal for precision pre-amplification found in spectrum analyzers, seismic detectors, and ADC and DAC buffer applications.

Features, Applications
FEATURES

Low noise 0.9 nV/Hz typical (1.2 nV/Hz maximum) input voltage noise at 1 kHz 50 nV p-p input voltage noise, 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 1000) 8 MHz bandwidth 10) 280 kHz full power bandwidth 20 V p-p 20 V/s slew rate Excellent dc precision 80 V maximum input offset voltage 1.0 V/C VOS drift Specified for 5 V and 15 V power supplies High output drive current 50 mA

The 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 dB in audio bandwidths give the AD797 the wide dynamic range necessary for preamps in microphones and mixing consoles. Furthermore, the AD797 has an excellent slew rate of 20 V/s and a 110 MHz gain bandwidth, which makes 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 - 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 50 mA output current drive and the specified power supply voltage range 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 - ADC/DAC buffers
