描述 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. 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).
