DESCRIPTION
The ADS5440 is a 13-bit 210 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 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.
