Precision op amp merges unity-gain stability, wide SFDR, low noise, speed

NORWOOD, Mass–The Analog Devices ADA4899-1 op amp simultaneously minimizes two key sources of error in precision measurement applications: noise and distortion. Further, the vendor claims that this op amp is the first unity-gain-stable device to reach voltage noise of just 1 nV/rt-Hz, along with a wide spurious free dynamic range (SFDR) of 117 dBc at 1 MHz. The op amp is especially well-suited for applications such as radar, ultrasound, and high-precision instrumentation.


High-end AC performance is matched by DC specifications such as 0.23 mV maximum offset voltage, and 1 &#956amp maximum input bias current. The ADA4899-1 is available in a 3mm x 3mm package as well as an 8-lead SOIC; the former has reduced lead inductance and better thermal characteristics, in addition to smaller size. Pricing for the op amp is $1.89 each, in 1000-piece orders.
