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 TQFP-100 PowerPAD™ package. The combination of the PowerPAD 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 industrial temperature range (–40°C to 85°C).
