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 Power PAD package. The device is built on Texas Instruments plementary bipolar process (Bi3) and is specified over the full industrial temperature range (- 40°C to +85°C).
