The ADS5474 device is a 14-bit, 400-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 500 MSPS. The ADS5474
device has an input buffer that isolates the internal switching of the onboard track and hold
(T&H) from disturbing the signal source while providing a high-impedance input. An internal
reference generator is also provided to simplify the system design. Designed with a 1.4-GHz input bandwidth for the conversion of wide-bandwidth signals that
exceed 400 MHz of input frequency at 400 MSPS, the ADS5474 device has outstanding low-noise
performance and spurious-free dynamic range over a large input frequency range.The ADS5474 device is available in an TQFP-80 PowerPAD package. The device is built on
Texas Instruments complementary bipolar process (BiCom3) and is specified over the full industrial
temperature range (–40°C to +85°C).
