DESCRIPTION  
The ADS5542 is a high-performance, 14-bit, 80MSPS 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 ADS5542 has  
excellent analog power dissipation of 545mW and output buffer power dissipation of 129mW from a 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 ADS5542 is available in a 64-pin TQFP PowerPAD package and is pin-compatible with the ADS5500, ADS5541,  
ADS5520, ADS5521, and ADS5522. This device is specified over the full temperature range of −40°C to +85°C.
