Overview
The ADA4937-2YCPZ-R7, produced by Analog Devices Inc., is a low noise, ultralow distortion, high-speed differential amplifier. It is part of the ADA4937-1/ADA4937-2 series, which are ideal for driving high-performance Analog-to-Digital Converters (ADCs) with resolutions up to 16 bits from dc to 100 MHz. These amplifiers are fabricated using Analog Devices' proprietary silicon-germanium (SiGe) complementary bipolar process, enabling very low levels of distortion and an input voltage noise of only 2.2 nV/√Hz.
