(1) These units are intended for engineering evaluation only.
They are processed to a non-compliant flow (e.g. no burn-in,
etc.) 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.
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).
