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 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 on full MIL specified temperature range of -55°C to 125°C or operating life.

3 Description

The ADS5400 is a 12-bit, 1-GSPS analog-to-digital converter (ADC) that operates from both a 5-V supply and 3.3-V supply, while providing LVDS-compatible digital outputs. The analog input buffer isolates the internal switching of the track and hold from disturbing the signal source. The simple 3-stage pipeline provides extremely low latency for time critical applications. Designed for the conversion of signals up to 2 GHz of input frequency at 1 GSPS, the ADS5400 has outstanding low noise performance and spurious-free dynamic range over a large input frequency range.

The ADS5400 is available in a 100-Pin Ceramic Nonconductive Tie-Bar Package. The combination of the ceramic package and moderate power consumption of the ADS5400 allows for operation without an external heatsink. The ADS5400 is built on Texas Instrument's complementary bipolar process (BiCom3) and is specified over the full military temperature range (–55°C to 125°C T_case).
