Rad-hard 17-bit 3-channel sigma-delta ADC at 3.2kS/s
Overview
Pacific Microchip Corp. is offering a radiation hardened 3-channel sigma-delta ADC. The ADC achieves 16.5-bit ENOB at 3.2kS/s rate. The ADC can operate over a temperature range from -50°C to 125°C. Radiation hardening is achieved through application of ELT structures, additional guard rings, redundant information storing, readout through majority voting and glitch filtering.
