3 Description
The ADS5463 is a 12-bit, 500-MSPS analog-to-digital
converter (ADC) that operates from both a 5-V supply
and 3.3-V supply, while providing LVDS-compatible
digital outputs from the 3.3-V supply. The ADS5463
input buffer isolates the internal switching of the
onboard track and hold (T and H) from disturbing the
signal source. An internal reference generator is also
provided to simplify the system design further. The
ADS5463 has outstanding low noise and linearity
over input frequency.
The ADS5463 is available in a 84-pin ceramic
nonconductive tie-bar package (HFG). The ADS5463
is built on 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).

(1) These units are intended for engineering evaluation only.
They are processed to a non-compliant flow (for example, no
burn-in, and so forth) and are tested to temperature rating of
25°C only. These units are not suitable for qualification,
production, radiation testing or flight use. Parts are not
warranted for performance on full MIL specified temperature
range of –55°C to 125°C or operating life.
(2) For all available packages, see the orderable addendum at
