ORDERING INFORMATION
When ordering, the converter part numbers are to be suffixed by
a two-letter code defining the accuracy grade, and a two digit
numeric code defining the signal/reference voltage and frequency.
All the standard options, and their option codes, are shown in
Figure 11. For nonstandard configurations, contact Analog
Devices.
For example, the AD2S44–TM12B is the correct part number
for a component that operates with 90 V signal, 115 V reference
synchro format inputs and yields a ±4.0 arc minutes accuracy
over the −55°C to +125°C temperature range processed to high
reliability standards.
