Monolithic. A one chip solution reduces the package size re-  
quired and increases the reliability.  
GENERAL D ESCRIP TIO N  
T he AD2S80A is a monolithic 10-, 12-, 14- or 16-bit tracking  
resolver-to-digital converter contained in a 40-pin DIP or 44-  
pin LCC ceramic package. It is manufactured on a BiMOS II  
process that combines the advantages of CMOS logic and bipo-  
lar high accuracy linear circuits on the same chip.  
Resolution Set by User . T wo control pins are used to select  
the resolution of the AD2S80A to be 10, 12, 14 or 16 bits al-  
lowing the user to use the AD2S80A with the optimum resolu-  
tion for each application.  
Ratiom etr ic Tr acking Conver sion. Conversion technique  
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.  
T he converter allows users to select their own resolution and dy-  
namic performance with external components. T his allows the users  
great flexibility in defining the converter that best suits their sys-  
tem requirements. T he converter allows users to select the reso-  
lution to he 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.  
D ynam ic P er for m ance 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. T he 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.  
T he AD2S80A converts resolver format input signals into a par-  
allel natural binary digital word using a ratiometric tracking con-  
version method. T his ensures high-noise immunity and tolerance  
of lead length when the converter is remote from the resolver.  
T he 10-, 12-, 14- or 16-bit output word is in a three-state digi-  
tal logic available in 2 bytes on the 16 output data lines. BYT E  
SELECT , ENABLE and INHIBIT pins ensure easy data trans-  
fer to 8- and 16-bit data buses, and outputs are provided to al-  
low for cycle or pitch counting in external counters.  
Velocity O utput. An analog signal proportional to velocity is  
available and is linear to typically one percent. T his can be used  
in place of a velocity transducer in many applications to provide  
loop stabilization in servo controls and velocity feedback data.  
Low P ower Consum ption. T ypically only 300 mW.  
An analog signal proportional to velocity is also available and  
can be used to replace a tachogenerator.  
Militar y P r oduct. T he AD2S80A is available processed in ac-  
cordance with MIL-ST D-883B, Class B.  
T he AD2S80A operates over 50 Hz to 20,000 Hz reference  
frequency.
