PRODUCTION DATA.
The ITEMP block in the PGA300 supplies a programmable current to an external temperature sensor such as an RTD temperature probe or NTC or PTC thermistor. The temperature-sensor current source is ratiometric to the accurate reference.
The value of the current can be programmed using the ITEMP_CTRL[2:0] bits in the TEMP_CTRL register.
