The ADA4899-1 is a high-performance operational amplifier from Analog Devices that features ultra-low noise, ultra-low distortion, and high speed. The device is available in an 8-lead LFCSP package and operates from a supply voltage range of 5V to 12V. It draws a maximum of 14.7mA of current. Typical applications include analog-to-digital converter drivers, instrumentation, filters, RF and baseband amplifiers, DAC buffers, and optical electronics.
The ADA4899-1 is an ultralow‑noise (1 nV/√Hz) and low‑distortion voltage‑feedback op‑amp designed for 16‑bit and 18‑bit systems. It features a linear input stage, internal compensation, and a disable mode that reduces input bias current by a factor of 60. The device is supplied by Analog Devices and is offered in both LFCSP and SOIC packages.
Key specifications include a 600 MHz –3 dB bandwidth, 310 V/µs slew rate, 14.7 mA supply current, 230 pV maximum offset voltage, and operation over a 4.5 V to 12 V supply range. It is rated for –40 °C to +125 °C and supports high‑speed applications such as ADC drivers, instrumentation, and optical electronics.
