– One Test Site
Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

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.
