MAX6690 Datasheet 2c ACcurate Remote/local Temperature Sensor

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2190; Rev 0; 10/01 2°C Accurate Remote/Local Temperature Sensor with SMBus Serial.

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.
