ADS7054: which ADC should be selected for optical grating transducer?

Part Number:ADS7054

Application: up to 50k Hz current control loop frequency and 300Hz bandwidth of position loop in Motor control, 12-bit, 2.2MSPS ADC integrated in  the MCU for current sampling. Which ADC can be recommended for displacement measuring of  optical grating transducer?

Input signal:differential input, 400-600mV amplitude

Amy Luo:

您好,

您的应用设计对ADC有哪些要求?比如说分辨率、采样率、数字通信接口类型等;

坦白说我不了解 optical grating transducer ,不清楚相对其他传感器它对ADC有什么特定要求,您可以详细说明吗以方便更好的选型?

下面是TI ADC的选型链接,主要分为3类,即高速ADC、精密ADC和隔离ADC,从这3类大类中选择一类,还可以根据网页左侧的筛选条件进一步筛选:
