2PCS analog device opamp AD797 AD797AR smt
OPA604, OP134, NE5532, TL071, AD827 are good opamp, however their specs are not top of the range if compare to AD797.
Have you ever think to replace them AD797?
AD797 is a very low noise, sweet and musical opamp. It is widely used in many high end preamplifiers and DACs. One of the best example is MBL from Germany. They have employed this opamp in their Pre-amp, Power amp and DACs.
If you are a DIYer, you should be very familiar with this opamp as they are widely discussed in .
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/?s and 110 MHz gain bandwidth make it highly suitable for low frequency ultrasound applications.
The AD797 is also useful in IR and sonar imaging applications where the widest dynamic range is necessary. The low distor-tion 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 used in critical applications such as seismic detection and 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.
