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.
