Rainbow-electronics MAX1619 Manual de usuario

________________General DescriptionThe MAX1619 is a precise digital thermometer that reportsthe temperature of both a remote sensor and its ownpackage

the MAX1619 can be forced to perform A/D conversionsvia the one-shot command, despite the RUN/STOP bitbeing high.Activate hardware standby mode by for

tems, since a second master could overwrite the com-mand byte without informing the first master. The temperature data format is 7 bits plus sign in t

If the remote channel is shorted (DXP to DXN or DXP toGND), the ADC reads 0000 0000 so as not to trip eitherthe THIGHor TLOWalarms at their POR settin

The address pin states are checked at POR and SPORonly, and the address data stays latched to reduce qui-escent supply current due to the bias current
