• Manufacturer Part Number: ad2s46
• Description: Low Cost, L6-bitsynchro Resolver -to-digital Converte
• Manufacturer: Analog Devices, Inc.

AD2S46
ORDERING INFORMATION
When ordering, the convener part numbers should be suffixed
by a tWo letter code defining the accuracy grade, and a two digit
numeric code defining the signal/reference voltage and fre-
quency. All the standard options and their option codes are
shown below. For options not shown, please contact Analog
Devices, Inc.
For example, the correct part number for a component to oper-
ate with a 90 V signal, 115 V reference synchro format inputs
and yield a :i:1.3 arc minute accuracy over the -55°C to +125OC
temperature range would be AD2S46TDI2. The same part pro-
cessed to high reliability standards would carry the designator B,
i.e., AD2S46TDl2B.

OTHER PRODUCTS
Many other products concerned with the conversion of synchro/
resolver data are manufactured by Analog Devices, some of
which are listed below. If you have any questions about our
products or require advice about their use for a particular appli-
cation please contact our Applications Engineering Department.
The SDCIRDC1740/41/42 are hybrid synchro/resolver-to-digital
converters with internal isolating micro transformers.
The SDCIRDCl76711768 are identical to tbe SDC/RDCI740
and dc error output.
The OSC17S8 is a hybrid sine/cosine power oscillator which can
The DRCl74S and DRCI746 are 14- and 16-bit natural binary
The AD2S44 and ADZS34 are 14 bit, dual channel synchro and
resolver-fa-digital converters. They are available with accuracy
series but with the additional features of analog velocity output
provide a maximum power output of 1.5 watts. The device op-
erates over a frequency range of 1 to 10 kHz.
latched output high power hybrid digital-to-resolver converters.
The accuracies available arc :i:2 and :i:4 arc minUtes and the
outputs can supply 2 VA at 7 V rms. Transformers are available
to convert the output to synchro or resolver format at high volt-
age levels.
The ADZS65/66 are similar to the DRCI745/46 but do not in-
clude the power output stage. These devices are available with
accuracy grades up to :j:1 arc minute.
grades up to =2.6 arc minutes and can be supplied in surface
mount packages.
The 2S80 series are monolithic ICs performing resolver-to-digital
conversion with accuracies up to :i:2 arc minutes and 16-bit
resolution.
