Overview
19-2190; Rev 0; 10/01 2°C Accurate Remote/Local Temperature Sensor with SMBus Serial Interface General Description 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 thermistors or thermocouples.
Remote accuracy is ±2°C for multiple transistor manufacturers, with no calibration needed.
The remote junction can also be a common-collector PNP, such as a substrate PNP of a microprocessor (µP).
The 2-wire serial interface accepts standard System Management Bus (SMBusTM), Wr...
