ADA4899-1

The ADA4899-1 is an ultralow noise (1 nV/Hz) and distortion (<−117 dBc @1 MHz) unity gain stable voltage feedback op amp, the combination of which 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. ADI's proprietary next generation XFCB process and innovative circuit design enable such high performance amplifiers.

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

The ADA4899-1 is available in a 3 mm * 3 mm LFCSP and a 8-lead SOIC package. Both packages feature an exposed metal paddle that improves heat transfer to the ground plane. This is a significant improvement over traditional plastic packages. The ADA4899-1 is rated to work over the extended industrial temperature range, −40°C to +125°C.
