RHF1201KSO1

Analog To Digital Converters (ADC) Overview

The RHF1201KSO1 is a radiation-hardened, 12-bit analog-to-digital converter (ADC) manufactured by STMicroelectronics. It operates at a sampling frequency of 50 Msps and utilizes pure CMOS 0.25 µm technology with a pipeline structure and digital error correction. The device dissipates 44 mW at 0.5 Msps and 100 mW at 50 Msps. It features an optimized 2 Vpp differential input, an internal voltage reference, and tri-state outputs for bus sharing. The component is housed in a hermetic ceramic SO-48 package and is designated as an engineering model.

Analog To Digital Converters (ADC) Feature Summary

• Radiation hardening providing immunity to total ionizing dose up to 300 kRad(Si) and single-event effects up to 120 MeV-cm2/mg.
• Pipeline architecture with proprietary track-and-hold structure designed for high linearity and IF-sampling applications.
• Adaptive power consumption capability allowing optimization across the entire sampling range via external resistor control.
• Integrated voltage reference network and data-ready synchronization signal to simplify system design.

Analog To Digital Converters (ADC) Applications

• Digital communication satellites
• Space data acquisition systems
• Aerospace instrumentation
• Nuclear and high-energy physics

Analog To Digital Converters (ADC) Procurement Notes

Verify that the specific order code matches the required quality level, as the KSO1 suffix indicates an engineering model rather than a flight-qualified unit. Confirm package specifications and lead finish details directly with the manufacturer or authorized distributors before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when radiation hardness is mandatory for space or high-radiation environments. Ensure the application requires a 12-bit resolution at speeds up to 50 Msps. Verify that the system can accommodate the 2.5 V analog supply and 2.5/3.3 V digital I/O requirements specified in the datasheet.

Analog To Digital Converters (ADC) Part Context

This part belongs to the RHF1201 family of rad-hard ADCs from STMicroelectronics. It shares the same core architecture and radiation specifications as other variants in the series but differs in qualification status and packaging options. The engineering model variant is intended for development and testing phases prior to flight hardware selection.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative rad-hard ADCs only if they meet the specific 300 kRad TID requirement and 50 Msps sampling rate constraints.
