Overview
The ADA4930-2YCPZ-R7, produced by Analog Devices Inc., is a high-performance, very low noise, and low distortion differential amplifier. It is designed to drive high-performance analog-to-digital converters (ADCs) with resolutions up to 14 bits from DC to 70 MHz. The amplifier features an adjustable output common mode, allowing it to match the input of the ADC, and an internal common-mode feedback loop that ensures exceptional output balance and suppression of even-order harmonic distortion products. Fabricated using Analog Devices' proprietary silicon-germanium (SiGe) complementary bipolar process, the ADA4930-2YCPZ-R7 achieves very low levels of distortion and an input voltage noise of only 1.2 nV/√Hz.
