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.
