AD2S80A
APPLICATIONS
Control Transformer
The ratio multiplier of the AD2S80A can be used independently
of the loop integrators as a control transformer. In this mode the
resolver inputs are multiplied by a digital angle any differ-
ence between and will be represented by the AC ERROR
output as SIN t sin ( – ) or the DEMOD output as sin ( – ).
To use the AD2S80A in this mode refer to the “Control Trans-
former” application note.
Dynamic Switching
In applications where the user requires wide band response from
the converter, for example 100 rpm to 6000 rpm, superior per-
formance is achieved if the converters control characteristics are

OTHER PRODUCTS
The AD2S82A is a monolithic, variable resolution 10-, 12-, 14-
and 16-bit resolver-to-digital converter in a 44-pin J-leaded
PLCC package. In addition to the AD2S80A functions it has a
VCO OUTPUT which is a measure of position within a LSB,
and a COMPLEMENT Data Output.
The AD2S81A is a low cost, monolithic, 12-bit resolver-to
digital converter in a 28-pin ceramic DIP package.
