Analog Devices' AD8599 dual operational amplifier is designed for medical, instrumentation, automated test equipment and other industrial applications that require low noise without sacrificing precision. The industry's only dual op amp to specify 1-nV/Hz voltage noise at 1kHz over a wide operating voltage range up to 36 V, the AD8599 lowers voltage noise by 80 percent as compared to standard amplifiers. Available in the same package as many single op amps, the AD8599 allows a much higher level of integration.

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 pre-amps, buffers for precision digital-to-analogue converters (DACs) and photodiode amplifiers. The AD8599 comes in an 8-lead SOIC (small outline integrated circuit) package, reducing board space requirements. It also reduces the cost of external components by including a compensation capacitor for unity gain stability.

The AD8599 is designed using Analog Devices’ proprietary iPolar™ high-voltage process technology, which provides best-in-class precision and gain stability. The device also offers 3.5-pA/√Hz current noise and less than 0.001 percent distortion, both of which are required to maintain the highest levels of precision for audio signal sources, transimpedance (current-to-voltage amplification) and other error feedback amplifier circuits that require high closed-loop gain and stability.
