PRODUCT HIGHLIGHTS
•
•
Complete Resolver-to-Digital Interface: The AD2S1200
provides the complete solution for digitizing resolver
signals (12-bit resolution) with on-board programmable
sinusoidal oscillator.
Ratiometric Tracking Conversion: This technique
provides continuous output position data without
conversion delay. It also provides noise immunity and
tolerance of harmonic distortion on the reference and
input signals.

Triple Format Position Data: Absolute 12-bit angular
binary position data accessed either via a 12-bit parallel
port or via a 3-wire serial interface. Incremental encoder
emulation in standard A QUAD B format, with direction
output is available.
Digital Velocity Output: 12-bit signed digital velocity,
twos complement format, accessed either via a 12-bit
parallel port or via a 3-wire serial interface.
Programmable Excitation Frequency: Excitation fre-
quency easily programmable to 10 kHz, 12 kHz, 15 kHz, or
20 kHz by using the frequency select pins.
System Fault Detection: A fault detection circuit will
detect any loss of resolver signals, out of range input
signals, input signal mismatch, or loss of position tracking.
