PRODUCT HIGHLIGHTS

GENERAL DESCRIPTION

1. Ratiometric tracking conversion. The Type II tracking loop

provides continuous output position data without

conversion delay. It also provides noise immunity and

tolerance of harmonic distortion on the reference and

input signals.

2. System fault detection. A fault detection circuit can sense

loss of resolver signals, out-of-range input signals, input

signal mismatch, or loss of position tracking. The fault

detection threshold levels can be individually programmed

by the user for optimization within a particular application.

3. Input signal range. The sine and cosine inputs can accept

differential input voltages of 3.15 V p-p 27%.

The AD2S1210 is a complete 10-bit to 16-bit resolution tracking

resolver-to-digital converter, integrating an on-board program-

mable sinusoidal oscillator that provides sine wave excitation

for resolvers.

The converter accepts 3.15 V p-p 27% input signals, in the range

of 2 kHz to 20 kHz on the sine and cosine inputs. A Type II

servo loop is employed to track the inputs and convert the input

sine and cosine information into a digital representation of the

input angle and velocity. The maximum tracking rate is 3125 rps.

4. Programmable excitation frequency. Excitation frequency

is easily programmable to a number of standard frequencies

between 2 kHz and 20 kHz.

5. Triple format position data. Absolute 10-bit to 16-bit angular

position data is accessed via either a 16-bit parallel port or a

4-wire serial interface. Incremental encoder emulation is in

standard A-quad-B format with direction output available.

6. Digital velocity output. 10-bit to 16-bit signed digital velocity

accessed via either a 16-bit parallel port or a 4-wire serial

interface.
