Dear Hui -
This would be 16 TMP devices and 16 2N3906 devices. (one for one relationship)
See figure 41 on page 29 for basic schematic.

Thanks for you reply.

Another question, when i use TMP451 with 2N3906 in an oil-bath, the local temperature is fixed at 25.0000℃，but the remote temperature is change around 25.0000℃, the reading is 25.0625℃,25.125℃,24.9375℃. Is this normal? why the remote channel cann't fixed at 25.00000℃

Hi Hui,

This is normal behavior for the temperature to vary around ~1 LSB from the actual value. This is sometimes caused by thermal or electrical noise in the system.

Thanks,
David
