ADA4930-1YCPZ

The ADA4930-1YCPZ is a very low noise low distortion high speed Differential Amplifier ideal for driving 1.8V high performance ADCs with resolutions up to 14 bits from DC to 70MHz. The adjustable output common mode allows the ADA4930-1 to match the input of the ADC. The internal common-mode feedback loop provides exceptional output balance, suppression of even-order harmonic distortion products and DC level translation. With the ADA4930-1, differential gain configurations are easily realized with a simple external feedback network of four resistors determining the closed-loop gain of the amplifier. The ADA4930-1 is 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 1.2nV/?Hz.
