RELIABILITY
The reliability of these products is very high due to the extensive
use of custom chip circuits that decrease the active component
count. Calculations of the MTBF figure under various environ-
mental conditions are available upon request from Analog
Devices.
Figure 9 shows the MTBF in years vs. case temperature for
Naval Sheltered conditions calculated in accordance with the
Mil-Hdbk-217E.

OTHER PRODUCTS
Analog Devices manufactures many other products concerned
with the conversion of synchro/resolver data, such as the
SDC/RDC1740 series and the AD2S80A series.
Hybrid
The SDC/RDC1740 is a hybrid synchro/resolver-to-digital
converter with internal isolating micro transformers.
Monolithic
The AD2S80A series are ICs performing resolver-to-digital
conversion with accuracies up to ±2 arc minutes and 16-bit
resolution.
Test and screening data supplied by request.
