The AD8599 dual op-amp is designed for medical, instrumentation, automated test equipment, and other industrial applications that require low noise without sacrificing precision. The AD8599 is the industry’s only dual op-amp to specify 1-nV/rootHz voltage noise at 1 kHz over a wide operating voltage range up to 36 V. It lowers voltage noise by 80% as compared to standard amplifiers.

The low noise and small footprint make the AD8599 easy to use. It is ideal for closed loop gain, error amplifier configurations and transimpedance applications, such as microphone preamps, buffers for precision DACs, and photodiode amplifiers. The AD8599 comes in an eight-lead SOIC package, reducing board space requirements. It also reduces the cost of external components by including a compensation capacitor for unity gain stability.

The op-amp is designed using the proprietary iPolar high-voltage process technology, which provides best-in-class precision and gain stability. The device also offers 3.5-pA/rootHz current noise and less than 0.001% distortion, both of which are required to maintain the highest levels of precision for circuits that require high closed-loop gain and stability.

The AD8599 costs $4.25 in 1,000-piece quantities.
