AD797 AD797AN AD797ANZ Ultralow Noise Op Amp IC BE73

AD797 AD797AN AD797ANZ Ultralow Noise Op Amp IC BE73 br br Description: br The AD797ANZ is an Ultralow Distortion Operational Amplifier ideal for use as a preamplifier. The low noise of 0.9nV/Hz and low total harmonic distortion of -120dB in audio bandwidths give the AD797 the wide dynamic range necessary for preamps in microphones and mixing consoles. It has an excellent slew rate of 20V/s and 110MHz gain bandwidth which makes it highly suitable for low frequency ultrasound applications. The ultralow noise op amp 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 analysers. Key features such as a 50mA output current drive and the specified power supply voltage range of 5 to 15V make the AD797 an excellent general-purpose amplifier. br 0.9nV/Hz Typical (1.2nV/Hz maximum) input voltage noise at 1kHz br 50nVp-p Input voltage noise, 0.1 to 10Hz br Excellent AC characteristics br 800ns Settling time to 16 bits (10V step) br 8MHz Bandwidth (G = 10) br 280kHz Full power bandwidth at 20V p-p br Excellent DC precision br 80V Maximum input offset voltage br 50mA High output drive current br br SPEK: br Number of Channels:1CH br THD plus Noise:0.000001 br Ib - Input Bias Current:1.5 uA br Vos - Input Offset Voltage:25 uV br Maximum Input Resistance:100 MOhms br Supply Voltage - Max:18 V br Supply Voltage - Min:5 V br Available Set Gain:20 V/uV br Bandwidth:8 MHz br Dual Supply Voltage:+/- 9 V, +/- 12 V, +/- 15 V br GBP - Gain Bandwidth Product:110 MHz br Input Voltage Range - Max:18 V br Operating Supply Current:8.2 mA br Operating Supply Voltage:5 V to 18 V br Output Current:50 mA br SR - Slew Rate:20 V/us br Supply Type:Dual
