DESCRIPTION
The ADS5522 is a high-performance, 12-bit, 80 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 little space, the
ADS5522 has excellent power consumption of 541 mW at 3.3-V single-supply voltage. This allows an even
higher system integration density. The provided internal reference simplifies system design requirements.
Parallel CMOS-compatible output ensures seamless interfacing with common logic.
The ADS5522 is available in a 64-pin TQFP PowerPAD package over the industrial temperature range.
