This report covers the radiation characterization results of the ADC168M102R-SEP which is a space grade 16-Bit 1-MSPS, 8-channel ADC that offers simultaneous sampling. The study was done to determine Total Ionizing Dose (TID) effects under low dose rate (LDR) and high dose rate (HDR) up to 30 Krad(Si) as a one-time characterization. The results show that all samples passed within the specified limits up to 30 Krad(Si).
In production, the Radiation Lot Acceptance Testing (RLAT) is performed using 5 units on every fab-lot to the specified rating of 30 krad(Si). Furthermore, the ADC168M102R-SEP has a Single Event Latch-Up (SEL) immunization up to 48MeV-cm2/mg which makes it suitable for Radiation Hardness Assured Space Applications.

The ADC168M102R-SEP is space grade 16-Bit 1-MSPS, ADC with eight pseudo- or four fully differential input channels grouped into two pairs for simultaneous signal acquisition analog inputs are maintained differentially to the input of the ADC. The input multiplexer can be used in either pseudo-differential mode, supporting up to four channels per ADC (4x2), or in fully-differential mode that allows to convert up to two inputs per ADC (2x2).
The ADC168M102R-SEP can be operated with independent analog and digital supplies. The analog supply (AVDD) can range from 2.7 V to 5.5V and the digital supply (DVDD) can range from 2.3V to 5.5V. The ADC168M102R-SEP is packaged in a 32-lead VQFN package.
