|High Temperature Analog-to-Digital Converter Reliability Testing|
|Keywords: High Temperature Electronics, High Temperature SOI CMOS, High Temperature Reliability|
|Initial test results have been previously reported for a high-temperature (225C) 12-bit analog-to-digital converter (HTADC12) fabricated using a production high-temperature silicon-on-insulator (SOI) CMOS process and assembled in hermetically sealed ceramic packages (ref. 1). This paper will present reliability test results for the HTADC12. This includes parametric and functional test results from 2000 hours of dynamic life test at 250C as well 1000 temperature cycles from -65C to 200C. Results of post-stress wirebond, die attach, and residual gas analysis testing are also provided. . 1.
