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.
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.
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

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.
An analog signal proportional to velocity is also available and
can be used to replace a tachogenerator.
T he AD2S80A operates over 50 Hz to 20,000 Hz reference
frequency.

Monolithic.
A one chip solution reduces the package size re-
quired and increases the reliability.
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.
Ratiometric T racking Conversion.
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.
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. 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.
Velocity Output.
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 Power Consumption.
T ypically only 300 mW.
Military Product.
T he AD2S80A is available processed in ac-
cordance with MIL-ST D-883B, Class B.
