MAX1618 Datasheet (Maxim) - Remote Temperature Sensor with SMBus Serial Interface

MAX1618, Remote Temperature Sensor with SMBus Serial Interface

The MAX1618 precise digital thermometer reports the temperature of a remote sensor.

The remote sensor is a diode-connected transistor *typically a low-cost, easily mounted 2N3904 NPN type *that replaces conventional thermistors or thermocouples.

Remote accuracy is ±3°C for multiple tra
