ADS5463
12 位 500MSPS ADC
The /ADS54RF63 is a 12-bit, 500-/550-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 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 compared 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 PowerPAD™ package. The ADS5463/ADS54RF63 is built on the Texas Instrument complementary bipolar process BiCom3 and specified over the full industrial temperature range -40°C to 85°C.
