The ADS5440 is a 13-bit 210 MSPS analog-to-digital converter(ADC) that operates from a 5V supply,while providing LVDS-compatible digital outputs from a 3.3V supply. The ADS5440 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 ADS5440 has outstanding low noise and linearity over input frequency.
The ADS5440 is available in an 80-pin TQFP PowerPAD™ package.The ADS5440 is built on state of the art Texas Instruments complementary bipolar process (BiCom3X) and is specified over the full industrial temperature range (40°C to 85°C).
