AD2S1200 12-Bit R/D Converter with Reference …
12-Bit R/D Converter with Reference Oscillator AD2S1200 . FEATURES GENERAL DESCRIPTION. Complete monolithic R/D Converter The AD2S1200 is a complete 12-Bit resolution tracking resolver- Parallel and serial 12-Bit data ports to-digital Converter , integrating an on-board programmable System fault detection sinusoidal oscillator that provides sine wave excitation for Absolute position and velocity outputs resolvers. An external MHz crystal is required to provide Differential inputs a precision time Reference . This clock is internally divided to 11 arc minutes of accuracy generate a MHz clock to drive all the peripherals. 1,000 rps maximum tracking rate, 12-Bit resolution The Converter accepts V p-p 10% input signals, in the Incremental encoder emulation (1,024 pulses/rev). range of 10 kHz to 20 kHz on the Sin and Cos inputs. A Type II. Programmable sinusoidal oscillator on-board servo loop is employed to track the inputs and convert the input Compatible with DSP and SPI interface standards Sin and Cos information into a digital representation of the kHz square wave output input angle and velocity.
