This ADC is one of a family of 12-, 13-, and 14-bit ADCs that operate from 210 MSPS to 550 MSPS. The ADS5463/ADS54RF63 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. The ADS54RF63 provides superior SFDR pared to the ADS5463 when the analog input frequency exceeds ~350 MHz or if operation up to 550 MSPS is required. The ADS5463/ADS54RF63 is available in a TQFP-80 Power PAD™ package. The ADS5463/ADS54RF63 is built on the Texas Instrument plementary bipolar process (Bi3) and specified over the full industrial temperature range (- 40°C to 85°C). A1 TH1 VREF Reference TH2 +S A2...
