 14  The AD4080 is a high speed, low noise, low distortion, 20-bit, Easy Drive,
 15  successive approximation register (SAR) analog-to-digital converter (ADC).
 16  Maintaining high performance (signal-to-noise and distortion (SINAD) ratio
 17  > 90 dBFS) at signal frequencies in excess of 1 MHz enables the AD4080 to
 18  service a wide variety of precision, wide bandwidth data acquisition
 19  applications.
