Analog Devices Inc. ADA4899-1 Unity-Gain Stable Operational Amplifiers

Analog Devices Inc. ADA4899-1 Unity-Gain Stable Operational Amplifiers (Op Amps) are an ultra-low noise (1nV/√Hz) and distortion (< −117dBc @ 1MHz) unity-gain stable voltage feedback op amp. This combination makes it ideal for 16-bit and 18-bit systems. The ADA4899-1 features a linear, low noise input stage and internal compensation that achieves high slew rates and low noise even at unity gain. The Analog Devices, Inc. proprietary next-generation XFCB process and innovative circuit design enable such high-performance amplifiers.

The ADA4899-1 drives 100Ω loads at breakthrough performance levels with only 15mA of supply current. With the wide supply voltage range (4.5V to 12V), low offset voltage (230μV maximum), wide bandwidth (600MHz), and slew rate (310V/μs), the ADA4899-1 is designed to work in the most demanding applications. The ADA4899-1 also features an input bias current cancellation mode that reduces input bias current by a factor of 60.

The Analog Devices Inc. ADA4899-1 is available in a 3mm x 3mm LFCSP and an 8-lead SOIC package. Both packages feature an exposed metal paddle that improves heat transfer to the ground plane, significantly improving over traditional plastic packages. The ADA4899-1 is rated to work over the extended industrial temperature range, from -40°C to +125°C.
