The ADA4899-1 is an ultralow noise (1 nV/√Hz) and distortion The ADA4899-1 is available in a 3 mm × 3 mm LFCSP and an (<−117 dBc at 1 MHz) unity-gain stable voltage feedback op 8-lead SOIC package. Both packages feature an exposed metal amp, the combination of which makes it ideal for 16-bit and paddle that improves heat transfer to the ground plane, which is 18-bit systems. The ADA4899-1 features a linear, low noise a significant improvement over traditional plastic packages. The input stage and internal compensation that achieves high slew ADA4899-1 is rated to work over the extended industrial rates and low noise even at unity gain. The Analog Devices, temperature range, −40°C to +125°C. Inc., proprietary next-generation XFCB process and innovative
