AD2S1210属于集成电路（IC）的ADC/DAC-特殊用途。由亚德诺半导体技术有限公司制造生产的AD2S1210ADC/DAC - 特殊用途该产品族中的产品可用于模拟和数字表示的信息转换，适用于特定用例，或集成了通用数据转换器中不常见的其他功能。例如针对超声或汽车雷达应用集成了低噪声放大器和可变增益级的器件、注重音频和视频的产品、在段码式显示器上集成显示测量值功能的器件、集成输入输出电气隔离的器件等。

GENERAL DESCRIPTION

The AD2S1210 is a complete 10-bit to 16-bit resolution tracking resolver-to-digital converter, integrating an on-board programmable 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.
