(1)These units are intended for engineering evaluation only. They are processed to a non-compliant flow (e.g. No Burn-In, etc.) and are tested to a temperature rating of 25°C only. These units are not suitable for qualification, production, radiation testing or flight use. Parts are not warranted for performance over the full MIL specified temperature range of –55°C to 125°C or operating life.
Description for the ADS5474-SP
The ADS5474 is a 14-bit, 400MSPS analog-to-digital converter (ADC) that operates from both a 5V supply and 3.3V supply while providing LVDS-compatible digital outputs. This ADC is one of a family of 12-, 13-, 14-bit ADCs that operate from 210MSPS to 500MSPS. 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 1.4GHz input bandwidth for the conversion of wide-bandwidth signals that exceed 400MHz of input frequency at 400MSPS, 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 non-conductive 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).
