ADA4927-1YCPZ-R2 Datasheet PDF - ADI

The ADA4927-1YCPZ-R2 is a Current Feedback Differential ADC Driver that is an ideal choice for driving high performance ADCs with resolutions up to 16-bits. The output common-mode level can easily be matched to the required ADC input common-mode levels. The internal common-mode feedback loop provides exceptional output balance and suppression of even-order distortion products. Differential gain configurations are easily realized using an external feedback network comprising four resistors. The current feedback architecture provides loop gain that is nearly independent of closed-loop gain, achieving wide bandwidth and low noise at higher gains and lower power consumption than comparable voltage feedback amplifiers. The ADA4927 is fabricated using the silicon germanium complementary bipolar process, enabling very low levels of distortion. The low DC offset and excellent dynamic performance makes it well suited for a wide variety of data acquisition and signal processing applications.
