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 θ are multiplied by a digital angle φ any differ-
ence between φ and θ will be represented by the AC ERROR
output as SIN ωt sin (θ–φ) or the DEMOD output as sin (θ–φ).
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
switched dynamically. This reduces velocity offset levels at low
tracking rates. For more information on the technique refer to
“Dynamic Resolution Switching Using the Variable Resolution
Monolithic Resolver-to-Digital Converters.”
OTHER PRODUCTS
The AD2S82A is a monolithic, variable resolution 10-, 12-, 14-
and 16-bit resolver-to-digital converter in a 44-terminal 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-lead ceramic DIP package.
