This document introduces the features and characteristics of the ADA4937-1 product, including extremely low harmonic distortion, low input voltage noise, high speed, and fast overdrive recovery
The ADA4937-1 is an ultralow distortion, high speed differential amplifier fabricated using proprietary silicon-germanium (SiGe) complementary bipolar process. It features extremely low harmonic distortion and low input voltage noise, making it ideal for driving high performance ADCs with resolutions up to 16 bits from dc to 100 MHz.
The device supports both single-supply operation (3.3 V to 5V) and offers adjustable gain via an external feedback network of four resistors. It is available in a Pb-free, 3 mm x 3 mm 16-lead LFCSP package.
