RH-DAC1612K1

Digital To Analog Converters Overview

The RH-DAC1612K1 is a radiation-hardened, high-resolution digital-to-analog converter manufactured by STMicroelectronics. It features a 16-bit resolution with a sampling rate of 12 kS/s and operates within a bandwidth up to 3 kHz. The device utilizes a sigma-delta architecture to achieve superior linearity and a signal-to-noise ratio of 96 dB at 3 kHz. It accepts single-ended inputs via an SPI interface and provides internally filtered voltage outputs. Power consumption is limited to 15 mW at the specified clocking speed. The component supports analog and digital supply voltages ranging from 3 V to 3.6 V and functions reliably in temperatures between -55°C and +125°C.

Digital To Analog Converters Feature Summary

• Radiation hardened design ensuring immunity to single-event latches up to 100 krad MIL-STD-883 1019.7 and characterized for single-event upsets.
• Sigma-delta architecture providing high precision with low noise and excellent signal-to-noise performance optimized for low-frequency applications.
• Flexible serial peripheral interface supporting both write and read modes with selectable straight binary or two’s complement input formats.

Digital To Analog Converters Applications

• Spacecraft instrumentation requiring radiation tolerance
• High-precision sensor signal conditioning in harsh environments
• Military avionics control systems

Digital To Analog Converters Procurement Notes

Verify the specific engineering model status and availability through authorized STMicroelectronics channels. Confirm that the CFlat-24 package matches your PCB footprint requirements. Ensure power supply rails strictly adhere to the 3 V to 3.6 V limits to prevent damage. Check for any required external reference components compatible with the RHF100 standard if higher precision is needed beyond internal capabilities.

Digital To Analog Converters Selection Notes

Select this component when radiation hardness is mandatory alongside high resolution. The 16-bit accuracy suits applications needing precise voltage generation at low speeds. Consider the 800 us settling time when designing for dynamic response requirements. Verify that the single-ended output configuration meets the load driving needs of the subsequent circuit stage without additional buffering.

Digital To Analog Converters Part Context

This part belongs to the RHRDAC1612 series of rad-hard DACs. It is distinct from standard commercial DACs due to its specialized radiation hardening processes. The K1 suffix typically denotes a specific packaging or testing variant within the engineering model scope. It serves as a niche solution for aerospace and defense sectors where reliability under ionizing radiation is critical.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacements must be sourced from STMicroelectronics' rad-hard portfolio. Any alternative must match the radiation hardness levels, pinout compatibility, and electrical specifications exactly.
