A Radiation Hardened Compact Multi-Channel DAC (RH-DAC)

Completed Technology Project

Project Introduction

This project seeks to design, fabricate and test a prototype of a radiation hardened, compact, low-power Multi-channel Digital-to-Analog Converter (RHDAC) application specific integrated circuit (ASIC) for miniaturized instrument electronics. The device will contain multiple digital-to-analog converter channels and a selectable serial interface and low-power consumption per channel.

We seek to develop a radiation hardened, compact, low-power Multi-channel Digital-to-Analog Converter (RHDAC) application specific integrated circuit (ASIC) for miniaturized instrument electronics. This project will address the need for space worthy, compact multi-channel data converters to reduce the size, mass and power of instrument electronics. The ASIC features are science driven based on applications in a realistic space environment such as detector threshold setting, current bias circuits and voltage stepping in high-voltage power supplies. It directly addresses the goal of reducing power, mass and volume for highly resource-constrained instruments. The main objective is to design, fabricate and test a radiation hardened multi-channel digital-to-analog converter ASIC that will enable and advance miniaturized instrument electronics.
