DESCRIPTION
The ADS5444 is a 13-bit 250 MSPS analog-to-digital converter (ADC) that operates from a 5 V supply, while
providing LVDS-compatible digital outputs from a 3.3 V supply. The ADS5444 input buffer isolates the internal
switching of the onboard track and hold (T&H) from disturbing the signal source. An internal reference generator
is also provided to further simplify the system design. The ADS5444 has outstanding low noise and linearity over
input frequency.
