Converter is small

Monolithic 12-bit, 500-Msample/s analog-to-digital converter offers 64.5-dB signal-to-noise ratio and up to 500-MHz input frequency in a 14 × 14-mm package. The ADS5463 provides 84-dBc SFDR, 10.5 ENOB, and an input bandwidth of 2 GHz while consuming 2.25-W power. It includes an internal reference generator and LVDS outputs with a half-clock-rate, data-ready signal to simplify designs.
