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

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

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-, 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 84-pin ceramic nonconductive tie-bar package (HFG). The device is built on Texas Instruments complementary bipolar process (BiCom3) and is specified over the full military temperature range (–55°C to +125°C Tcase).
