DESCRIPTION
The ADS5474 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 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. 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 has outstanding low-noise performance and spurious-free dynamic
range over a large input frequency range.
The ADS5474 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).
