The ADS5521 is a high-performance, 12-bit, 105MSPS 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 ADS5521
has excellent power consumption of 700mW at 3.3V 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 ADS5521 is available in a 64-pin TQFP PowerPAD package and is pin-compatible with the ADS5500, ADS5541,
ADS5542, ADS5520, and ADS5522. This device is specified over the full temperature range of −40°C to +85°C.
