AD2S1205WSTZ

数据采集ADC/DAC – IC 12-Bit R/D Cnvtr

12-Bit RDC  with Reference Oscillator

GENERAL DESCRIPTION AD2S1205WSTZ

The AD2S1205 is a complete 12-bit resolution tracking

resolver-to-digital converter that contains an on-board

programmable sinusoidal oscillator providing sine wave

excitation for resolvers.

The converter accepts 3.15 V p-p ± 27% input signals on the Sin

and Cos inputs. A Type II tracking loop is employed to track the

inputs and convert the input Sin and Cos information into a digital

representation of the input angle and velocity. The maximum

tracking rate is a function of the external clock frequency. The

performance of the AD2S105 is specified across a frequency

range of 8.192 MHz ± 25%, allowing a maximum tracking rate

of 1250 rps.
