ANALOG DEVICES ADA4939-2YCPZ-R7 Operational Amplifier, 2 Channels, 1.4 GHz, 6.8 kV/µs, 3V to 5.25V, LFCSP-EP, 24 Pins

ADA4939-2YCPZ-R7 is an ultralow distortion, differential ADC driver. It is a low noise, ultralow distortion, high speed differential amplifier. It is an ideal choice for driving high performance ADCs with resolutions upto 16bits from DC to 100MHz. The output common-mode voltage is user adjustable by means of an internal common-mode feedback loop, allowing the device output to match the input of the ADC. The internal feedback loop also provides exceptional output balance as well as suppression of even-order harmonic distortion products. The low DC offset and excellent dynamic performance of the device makes it well suited for a wide variety of data acquisition and signal processing applications. It is used in applications such as ADC drivers, single-ended-to-differential converters, IF and baseband gain blocks, differential buffers, line drivers.
