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 Tcase).
