Who makes the TL501 - Texas Instruments???

I'm very curious about how you get the thermocouple signal into this
chip.  I have heard you have to connect thermocouples with particular
metals and sometimes use cold junctions and other complex and
expensive measures.  How are you handling these issues?  Is the TL501
specialized for thermocouples or is it simply a general purpose A/D?
