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 is also 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 can also 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 industrial

temperature range (–40

°C to 85°C).
