compared to this one

The price is in Singapore dollar (1.2 sin dollar = 1 us dollar)

Thanks!

The more expensive one lists automotive applications. That usually brings the price of an IC way up. It also looks like a hermetically sealed mil-spec chip as well which usually brings the price of an IC WAAAAYYYY up.
