a
Variable Resolution,
Resolver-to-Digital Converter
AD2S83
GENERAL DESCRIPTION
The AD2S83 is a monolithic 10-, 12-, 14- or 16-bit tracking
resolver-to-digital converter.
The converter allows users to
select their own resolution and dy-
namic performance with external components.
The converter 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 AD2S83 converts resolver format input signals into a paral-
lel natural binary digital word using a ratiometric tracking con-
version method. This ensures high noise immunity and tolerance of
long leads allowing the converter to be located remote from the
resolver.
The position output from the converter is presented via 3-state
output pins which can be configured for operations with 8- or
16-bit bus. BYTE SELECT,
ENABLE
and
INHIBIT
pins
ensure easy data transfer to 8- and 16-bit data bus, and outputs
are provided to allow for cycle or pitch counting in external
counters.
A precise analog signal proportional to velocity is also available
and will replace a tachogenerator.
The AD2S83 operates over reference frequencies in the range
0 Hz to 20,000 Hz.
PRODUCT HIGHLIGHTS
High Accuracy Velocity Output.
A precision analog velocity
signal with a typical linearity of
±
0.1% and reversion error less
than
±
0.3% is generated by the AD2S83. The provision of this
signal removes the need for mechanical tachogenerators used in
servo systems to provide loop stabilization and speed control.
Resolution Set by User.
Two control pins are used to select
the resolution of the AD2S83 to be 10, 12, 14 or 16 bits allow-
ing optimum resolution for each application.
Ratiometric Tracking Conversion
.
This technique provides
continuous output position data without conversion delay. It
also provides noise immunity and tolerance of harmonic distor-
tion 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 component
values are easy to select using the free component selection
software design aid.

Information on the models available is given in the Ordering
