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. This ADC is one of a family of 12-, 13-, and 14-bit  
ADCs that operate from 210 MSPS to 500 MSPS. 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 with a 2.3-GHz input bandwidth for the conversion of signals that exceed 500MHz of input center  
frequency at 500 MSPS, the ADS5463 has outstanding low noise performance and spurious-free dynamic range  
over a large input frequency range.  
The ADS5463 is available in a TQFP-80 PowerPAD™ package. The ADS5463 is built on Texas Instrument's  
complementary bipolar process (BiCom3) and is specified over the full industrial temperature range (–40°C to  
85°C).
