DESCRIPTION/ORDERING INFORMATION
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. The ADS5463 input buffer isolates the internal
switching of the onboard track and hold (T&H) from disturbing the signal source while providing a high
impedance input. An internal reference generator also is provided to simplify the system design.
Designed to optimize conversion of wide-bandwidth signals up to 500-MHz of input frequency at 500 MSPS, the
ADS5463 has outstanding low noise and linearity over a large input frequency range. Input signals above 500
MHz also can be converted due to the large input bandwidth of the device.
The ADS5463 is available in an 80-pin TQFP PowerPAD™ package. The ADS5463 is built on state-of-the-art
Texas Instruments complementary bipolar process (BiCom3X) and is specified over the full extended
temperature range (–55°C to 125°C).
