Part Number | AD2S93 |

Manufacturer | Analog Devices (https://www.analog.com/) |

Description | The AD2S93 is a complete 14-bit resolution tracking LVDT-todigital converter. A Type II tracking loop is employed to track the A–B input and produce a digital output equal to (A–B)/ (REF/2), where REF is a fixed amplitude ac reference phase coherent with the A–B input. This allows the measurement o... |

Two transforms are included in the AD2S100. The first is the Clarke transform which computes the sine and cosine orthogonal components of a three-phase input. These signals represent real and imaginary components which then form the input to the Park transform. The Park tra... |

12-Bit R/D Converter with Reference OscillatorThe AD2S1200 is a complete 12-bit resolution tracking resolverto-digital converter, integrating an on-board programmable sinusoidal oscillator that provides sine wave excitation for resolvers. An external 8.192 MHz crystal is required to provide a precision time reference. This clock is internally divided to generate a 4.096 MHz clock to drive all the peripherals. The converter accepts 3.6 V p-p ± 10% input signals, in the range of 10 kHz to 20 kHz on the Sin and Cos inputs. A Type II servo 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 bandwidth of the converter is set internally to 1.7 kH... |
