GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD2S83 is a monolithic 10-, 12-, 14- or 16-bit tracking  
resolver-to-digital converter.  
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.  
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.  
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.  
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.  
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.  
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.  
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.  
A precise analog signal proportional to velocity is also available  
and will replace a tachogenerator.  
MODELS AVAILABLE  
Information on the models available is given in the Ordering  
Guide.  
The AD2S83 operates over reference frequencies in the range  
0 Hz to 20,000 Hz.
