The AD8599 is a dual, very low noise, low distortion operational amplifier ideal for use as a preamplifier. Its low noise of 1 nV/√Hz and low harmonic distortion of -105 dB THD @ 20 kHz make it an ideal choice for many high-performance applications.
The AD8599 dual operational amplifier offers exceptionally low noise (1 nV/√Hz at 1 kHz) and low total harmonic distortion (‑105 dB THD at 20 kHz), making it suitable for high‑performance audio, medical and precision instrumentation. It operates from a single +15 V supply, provides a slew rate of 16 V/µs, and remains stable at unity gain.
Typical applications include professional audio preamplifiers, ATE/precision testers, imaging systems, and medical/physiological measurement equipment. The device is supplied in an 8‑lead SOIC package and is rated for operation from –40 °C to +125 °C.
