The document introduces the features and characteristics of the ADA4937-1 product, including extremely low harmonic distortion, low input voltage noise, high speed, fast response, adjustable gain, single-ended input and differential output.
The ADA4937-1 is a low noise, ultralow distortion, high speed differential amplifier fabricated using Analog Devices' proprietary silicon-germanium (SiGe) complementary bipolar process. It is an ideal choice for driving high performance ADCs with resolutions up to 16 bits from dc to 100 MHz. The device features an adjustable output common-mode voltage to match the input of the ADC and includes an internal common-mode feedback loop for exceptional output balance and suppression of even-order harmonic distortion products.
