DESCRIPTION

The ADS5500 is a high-performance, 14-bit, 125MSPS 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 ADS5500

has excellent power consumption of 780mW 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 ADS5500 is available in a 64-pin TQFP PowerPAD package and is specified over the full temperature range of

−40

°C to +85°C.
