ADS5444
13 位 250MSPS ADC
The is a 13-bit 250 MSPS analog-to-digital converter ADC that operates from a 5 V supply, while providing LVDS-compatible digital outputs from a 3.3 V supply. The ADS5444 input buffer isolates the internal switching of the onboard track and hold T&H from disturbing the signal source. An internal reference generator is also provided to further simplify the system design. The ADS5444 has outstanding low noise and linearity over input frequency.
The ADS5444 is available in an 80-pin TQFP PowerPAD package. The ADS5444 is built on a state of the art Texas Instruments complementary bipolar process BiCom3X and is specified over the full industrial temperature range -40°C to 85°C.
