Overview

The RHF1201KSO1 is a radiation-hardened, 12-bit pipelined analog-to-digital converter designed for high-reliability aerospace applications. It features a wide sampling range tested up to 50 Msps while utilizing Optimwatt technology to scale power consumption from 44mW to 100mW based on the sampling rate.

Why Choose This Part

This ADC is QML-V qualified and offers exceptional radiation tolerance, including latchup immunity up to 120 MeV-cm2/mg and TID resilience up to 300 kRad. The hermetic ceramic 48-SO package ensures long-term reliability in vacuum and extreme temperature conditions from -55C to 125C.

Applications

Satellite Telemetry
Processing sensor and health data in Low Earth Orbit (LEO) and Geostationary (GEO) satellite systems.
Space Imaging Systems
High-speed digitization of image sensor data in radiation-heavy environments.
Nuclear Instrumentation
Data acquisition for monitoring equipment in environments subject to high total ionizing dose (TID).
Military Communications
Reliable signal conversion for secure radio links requiring MIL-STD compliance.

Getting Started

Designers should prioritize low-impedance power plane routing and use the internal reference with external biasing for maximum stability. Evaluation usually requires custom radiation-tolerant PCB layouts as typical commercial dev boards do not meet the thermal or signal integrity requirements for this class of component.
