DESCRIPTION

The ADS5553 is a high-performance, dual channel, 14 bit, 65 MSPS analog-to-digital converter (ADC). To provide

a complete solution, each channel includes a high-bandwidth linear sample-and-hold stage (S&H) and an internal

reference. Designed for applications demanding high dynamic performance in a small space, the ADS5553 has

excellent power consumption of 0.9 W at 3.3 V single-supply voltage. This allows an even higher system integration

density. The provided internal reference simplifies system design requirements, yet an external reference can be

used optionally to suit the accuracy and low drift requirements of the application. The outputs are parallel CMOS

compatible.

The ADS5553 is available in a 80 lead TQFP PowerPAD package and is specified over the full temperature range

of −40°C to 85°C.
