3 Description
The ADS5400 device 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 HTQFP-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).
