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 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).

ADS5400-SP_Radiation_Report
 
Note: The following radiation test results are provided for information only, as these devices are not Radiation Hardness
Assured (RHA) at this time.
 
Samples of the 5962-0924001VXC, ADS5400-SP, device have been evaluated to determine performance effects
after Total Ionizing Dose (TID) radiation exposure. Twenty samples were exposed under biased conditions at 50
rad(Si)/sec. Bias conditions were the same as the circuit used for burn-in.
 
Radiation exposure for all samples was performed at Radiation Assured Device, Inc. in Colorado Springs, CO. Pre
and post radiation electrical testing was performed by Texas Instruments in Dallas, TX.
 
The TID samples were pulled from the initial qualification lot after completing normal class-V processing
(assembly, burn-in, full-temp testing), and serialized datalogs were collected at 25C before and after radiation
exposure. The electrical testing results are included in the release documentation. The test results are summarized
below.

Description
 
Optimized for high-volume consumer applications, this solution extends the advantages of transition mode—high
efficiency with low-cost components—to higher power ratings than previously possible. By utilizing a Natural
Interleaving technique, both channels operate as masters (that is, there is no slave channel) synchronized to the
same frequency. This approach delivers inherently strong matching, faster responses, and ensures that each
channel operates in transition mode.
 
Complete system-level protections feature input brownout, output over-voltage, open-loop, overload, soft-start,
phase-fail detection, and thermal shutdown. The additional FailSafe over-voltage protection (OVP) feature
protects against shorts to an intermediate voltage that, if undetected, could lead to catastrophic device failure.
