MAX6690 Datasheet (Maxim) - 2C Accurate Remote/Local Temperature Sensor

MAX6690, 2C Accurate Remote/Local Temperature Sensor

The MAX6690† is a precise digital thermometer that reports the temperature of both a remote P-N junction and its own die.

The remote junction can be a diode-connected transistor *typically a low-cost, easily mounted 2N3904 NPN type or 2N3906 PNP type *that replaces conventional thermis
