ADS5474HFG/EM

Analog To Digital Converters (ADC) Overview

The ADS5474HFG/EM is a Class V, radiation-hardened, 14-bit analog-to-digital converter (ADC) operating at 400 MSPS. It features an input bandwidth of 1.28 GHz and delivers 10.9 bits of effective number of bits (ENOB). The device utilizes a 3.3-V digital supply for LVDS-compatible outputs and operates within a military temperature range of –55°C to +125°C Tcase. It is housed in an 84-pin ceramic nonconductive tie-bar package (HFG). Engineering evaluation samples are available with radiation hardness assurance up to 100 krad (Si), ELDRS-free performance, and characterized single-event effects.

Analog To Digital Converters (ADC) Procurement Notes

The /EM suffix indicates engineering evaluation samples processed via a non-compliant flow. These units lack burn-in and are tested only at 25°C. They are not suitable for qualification, production, radiation testing, or flight use. Performance over the full MIL specified temperature range or operating life is not warranted.

Analog To Digital Converters (ADC) Selection Notes

Verify that the application requires Class V radiation tolerance and the specific 84-pin HFG ceramic package. Confirm compatibility with the 5-V analog and 3.3-V digital supply architecture. Ensure the system can accommodate the 10.9 ENOB specification rather than ideal 14-bit accuracy.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS5474-SP family of high-speed ADCs. It is pin-similar and compatible with the 12-bit ADS5463-SP and 14-bit ADS5444-SP devices, facilitating potential design upgrades or downgrades within radiation-tolerant systems.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADS5463-SP and ADS5444-SP. Note that these variants offer different resolutions (12-bit and 14-bit respectively) and may have distinct electrical characteristics compared to the ADS5474-SP.
