GENERAL DESCRIPTION
The AD9446 is a 16-bit, monolithic, sampling analog-to-digital converter (ADC) with an on-chip track-and-hold circuit. It is optimized for performance, small size, and ease of use. The product operates up to a 100 MSPS, providing superior SNR for instrumentation, medical imaging, and radar receivers employing baseband (<100 MHz) IF frequencies.

FEATURES
   100 MSPS guaranteed sampling rate (AD9446-100)
   83.6 dBFS SNR with 30 MHz input (3.8 V p-p input, 80 MSPS)
   82.6 dBFS SNR with 30 MHz input (3.2 V p-p input, 80 MSPS)
   89 dBc SFDR with 30 MHz input (3.2 V p-p input, 80 MSPS)
   95 dBFS 2-tone SFDR with 9.8 MHz and 10.8 MHz (100 MSPS)
   60 fsec rms jitter
   Excellent linearity
      DNL = ±0.4 LSB typical
      INL = ±3.0 LSB typical
   2.0 V p-p to 4.0 V p-p differential full-scale input
