Specified for ±5 V and ±15 V power supplies
High output drive current of 50 mA 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 in audio bandwidths
give the AD797 the wide dynamic range necessary for preamps …
