DESCRIPTION/ORDERING INFORMATION
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.

The ADS5444 is available in a 84 pin ceramic nonconductive tie-bar package (HFG). The ADS5444 is built on a
state-of-the-art Texas Instruments complementary bipolar process (BiCom3X) and is specified over the full
military temperature range (–55°C to 125°C T_case).
