HD3, -60 GENERAL DESCRIPTION -65 The ADA4937-1/ADA4937-2 are fabricated using Analog Devices,
Inc., proprietary silicon-germanium (SiGe), complementary
bipolar process, enabling them to achieve very low levels of
distortion with an input voltage noise of only 2.2 nV/√Hz.
The low dc offset and excellent dynamic performance of the
ADA4937-1/ADA4937-2 make them well-suited for a wide
variety of data acquisition and signal processing applications. -75 …
