AD2S1200: 12位R/D转换器,内置参考振荡器
AD2S1200是一款12位分辨率旋变数字转换器,集成片上可编程正弦波振荡器,为旋变器提供正弦波激励。它需要一个外部8.192 MHz晶振,以提供精密时间参考。此时钟在内部进行分频,产生一个4.096 MHz时钟以驱动所有外设。转换器的正弦和余弦输入端允许输入3.6 V p-p ±10%、频率为10 kHz至20 kHz范围内的信号。Type II伺服环路用于跟踪输入信号,并将正弦和余弦输入端的信息转换为输入角度和速度所对应的数字量。利用外部8.192 MHz晶振,转换器的带宽内部设置为1.7 kHz。最大跟踪速率为1,000 rps。
The AD2S1200 is a complete 12-bit resolution tracking resolver-to-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 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 kHz with an external 8.192 MHz crystal. The maximum tracking rate is 1,000 rps
