New ADC drivers from Analog Devices to step up the performance of ADCs

If the performance of Analog to Digital Converters is curtailed due to signal distortion and noise at input, you can try these new ADC drivers from Analog Devices to get the best out of your ADCs. Analog devices new ADC drivers ADA4937-1 and ADA4938-1 offer low signal distortion and noise.
ADA4937-1 distortion levels are -120/-102 dBc at 10 MHz, -98/-100 dBc at 40 MHz and -84/-90 dBc at70 MHz where as ADA4938-1 distortion levels are -112/-108 dBc at 10 MHz, -96/-93 dBc at 30 MHz and -79/-81 dBc at 50 MHz.

ADA4937-1 works from single supply voltage of 3V and 5V and ADA4938-1 can operate from a dual supply voltage of 5V to 10V.
Both the devices has built in common mode feedback architecture, this helps in keeping the signal range with in the limits of ADC inputs and save you a coupling capacitor. The frequency range these drivers can operate is DC to 100 MHz.
