ADA4927 Ultralow Distortion Differential ADC Driver
Analog Devices' single ADA4927-1 and dual ADA4927-2 high-speed, ultralow-distortion, current-feedback differential ADC drivers
The ADI's single ADA4927-1 and dual ADA4927-2 high-speed, ultralow-distortion, current-feedback differential ADC drivers are designed to interface directly with high-performance ADCs having up to 16-bit resolution from dc to 100 MHz. They feature 1400 MHz bandwidth, 5000 V/µs slew rate, 2.6 ns settling time, 117 dBc SFDR at 10 MHz, and 1.3 nV/√Hz noise. The drivers are stable for fractional differential gains, unity gain, and gains greater than one. Gain is set by two pairs of external resistors. The common-mode output voltage can be set to match the input of the ADC.
