The ADS5520 is a high-performance, 12-bit, 125 MSPS analog-to-digital converter (ADC). To provide a complete converter solution, it includes a high-bandwidth linear sample-and-hold stage (S&H) and internal reference. Designed for applications demanding the highest speed and highest dynamic performance in very little space, the ADS5520 has excellent analog power dissipation of 578 mW and output buffer power dissipation of 202 mW from the 3.3-V single-supply voltage. This allows an even higher system integration density. The provided internal reference simplifies system design requirements. The parallel CMOS compatible outputs ensure seamless interfacing with common logic.
