ADA4930-2YCPZ-R2

ADA4930-2 is a very low noise, low distortion, high speed differential amplifier. This is an ideal choice for driving 1.8V high performance ADCs with resolutions up to 14bits from DC to 70MHz. The adjustable output common mode allows this 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 this, differential gain configurations are easily realized with a simple external feedback network of four resistors determining the closed-loop gain of the amplifier. The low DC offset and excellent dynamic performance of this make them well suited for a wide variety of data acquisition and signal processing applications. Typical applications are ADC drivers, single-ended-to-differential converters, IF and baseband gain blocks, differential buffers, line drivers.
