I've seen AD7193(8ch) supports all type of RTD,TC.
However I need more channel as like AD7173-8 or AD7175-8.
Do they support all type of RTD,TC as well as AD7193?
AD717x series has excellent performance in terms of speed and noise and which can be use to different types of applications such as temperature and pressure measurements. However, it does not have an internal PGA that is very useful for RTDs and TCs measurements. Because the output from these sensors are small, an external circuitry might be necessary to amplify the signal from TCs or RTDs. You may want to consider using AD7124-8 instead which includes most of the required system building blocks for TCs and RTDs measurements that will make your design simple and which eliminates the needs for external circuitry. We also have an available reference circuits on the AD7124 product page that can help you regarding this matter. Please see link below and look for the reference designs section. http://www.analog.com/en/products/analog-to-digital-converters/precision-adc-10msps/ad7124-8.html#product-designs
