17.2. LM35DZ
Figure 17.2. DAEnetIP2 v2 and LM35DZ/LM34DZ
When using LM35DZ all the disadvantages of LM335 are avoided – there is no need of current
resistor (as this sensor does not work as zener diode) neither output divisor. Also its initial error is
better than LM335. The only disadvantage is the minimal voltage is 4VDC and this makes the
connection to DAEnetIP2 v2 more difficult (it cannot be connected directly with only single IDC
connector to P6). The 27K resistor acts like protection of the analog input P6.X and it is strongly
recommend.
