超低失真电流反馈差分ADC驱动器 Ultralow Distortion Current Feedback Differential ADC Driver
Product Details
The ADA4927 is a low noise, ultralow distortion, high speed, current feedback differential amplifier that is an ideal choice for driving high performance ADCs with resolutions up to 16 bits from dc to 100 MHz. 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, low distortion, and low noise at higher gains and lower power consumption than comparable voltage feedback amplifiers.
The ADA4927 is fabricated using the Analog Devices, Inc., silicon-germanium complementary bipolar process, enabling very low levels of distortion with an input voltage noise of only 1.3 nV/√Hz. The low dc offset and excellent dynamic performance of the ADA4927 make it well suited for a wide variety of data acquisition and signal processing applications.
The ADA4927-1 is available in a Pb-free, 3 mm × 3 mm 16-lead LFCSP, and the ADA4927-2 is available in a Pb-free, 4 mm × 4 mm 24-lead LFCSP. The pinouts are optimized to facilitate printed circuit board PCB layout and to minimize distortion. They are specified to operate over the −40°C to +105°C temperature range.
