Data Sheet Unity-Gain Stable, Ultralow Distortion, 1 nV/Hz Voltage Noise, High Speed Op Amp ADA4899-1 FEATURES Unity-gain stable Ultralow noise: 1 nV/√Hz, 2.6 pA/√Hz Ultralow distortion −117 dBc at 1 MHz High speed −3 dB bandwidth: 600 MHz (G = +1) Slew rate: 310 V/μs Offset voltage: 230 μV maximum Low input bias current: 100 nA Wide supply voltage range: 5 V to 12 V Supply current: 14.7 mA High performance pinout Disable mode APPLICATIONS Analog-to-digital drivers Instrumentation Filters IF and baseband amplifiers DAC buffers Optical electronics GENERAL DESCRIPTION The ADA4899-1 is an ultralow noise (1 nV/√Hz) and distortion (<−117 dBc at 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. The Analog Devices, Inc., proprietary next-generation XFCB process and innovative circuit design enable such high performance amplifiers. The ADA4899-1 drives 100 Ω 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 μV maximum), wide bandwidth (600 MHz), and slew rate (310 V/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. 05720-001 ...
