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.
