DESCRIPTION
The ADS5541 is a high-performance, 14-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 a small space, the ADS5541 has
excellent analog power dissipation of 571mW at 3.3V
single-supply voltage. This allows an even higher
system integration density. The provided internal
reference simplifies system design requirements.
The parallel CMOS compatible outputs ensure
seamless interfacing with common logic.
The ADS5541 is available in a TQFP-64 PowerPAD
package over the industrial temperature range.
