Variable Resolution, Monolithic
Resolver-to-Digital Converters
AD2S81A/AD2S82A
An analog signal proportional to velocity is also available and
can be used to replace a tachogenerator.
PRODUCT HIGHLIGHTS
Monolithic.
A one-chip solution reduces the package size re-
quired and increases the reliability.
Resolution Set by User.
Two control pins are used to select
the resolution of the AD2S82A to be 10, 12, 14 or 16 bits al-
lowing the user to use the AD2S82A with the optimum resolu-
tion for each application.
Ratiometric Tracking Conversion.
provides continuous output position data without conversion
delay and is insensitive to absolute signal levels. It also provides
good noise immunity and tolerance to harmonic distortion on
the reference and input signals.
Dynamic Performance Set by the User.
By selecting exter-
nal resistor and capacitor values the user can determine band-
width, maximum tracking rate and velocity scaling of the
converter to match the system requirements. The external com-
ponents required are all low cost, preferred value resistors and
capacitors, and the component values are easy to select using
the simple instructions given.
Velocity Output.
An analog signal proportional to velocity is
available and is linear to typically one percent. This can be used
in place of a velocity transducer in many applications to provide
loop stabilization in servo controls and velocity feedback data.
Low Power Consumption.
Typically only 300 mW.
MODELS AVAILABLE
Information on the models available is given in the Ordering
Guide.
GENERAL DESCRIPTION
The AD2S82A is a monolithic 10-, 12-, 14- or 16-bit tracking
resolver-to-digital converter contained in a 44-lead J leaded
PLCC package. Two extra functions are provided in the new
surface mount package–COMPLEMENT and VCO output.
The AD2S81A is a monolithic 12-bit fixed resolution tracking
resolver-to-digital converter packaged in a 28-lead DIP.
The converters allow users to
select their own dynamic performance
with external components.
This allows the users great flexibility in
defining the converter that best suits their system requirements.
The AD2S82A allows users to select the resolution to be 10, 12,
14 or 16 bits and to track resolver signals rotating at up to 1040
revs per second (62,400 rpm) when set to 10-bit resolution.
The AD2S81A and AD2S82A convert resolver format input
signals into a parallel natural binary digital word using a ratio-
metric tracking conversion method. This ensures high-noise
immunity and tolerance of lead length when the converter is
remote from the resolver.
The output word is in a three-state digital logic form available in
two bytes on the 16 output data lines for the AD2S82A and on
eight output data lines for the AD2S81A. BYTE SELECT,
ENABLE
and
INHIBIT
pins ensure easy data transfer to 8- and
16-bit data buses, and outputs are provided to allow for cycle or
pitch counting in external counters.
