ADS5474 - 14-Bit, 400-MSPS Analog-to-Digital Converter (ADC)

The ADS5474 device is a 14-bit, 400-MSPS analog-to-digital converter (ADC) that operatesfrom both a 5-V supply and 3.3-V supply while providing LVDS-compatible digital outputs. This ADCis one of a family of 12-, 13-, and 14-bit ADCs that operate from 210 MSPS to 500 MSPS. The ADS5474device 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 internalreference generator is also provided to simplify the system design.

Designed with a 1.4-GHz input bandwidth for the conversion of wide-bandwidth signals thatexceed 400 MHz of input frequency at 400 MSPS, the ADS5474 device has outstanding low-noiseperformance 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 onTexas Instruments complementary bipolar process (BiCom3) and is specified over the full industrialtemperature range (–40°C to +85°C).
