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).
