MAX1668 Datasheet (Maxim) - Multichannel Remote/Local Temperature Sensors

MAX1668, Multichannel Remote/Local Temperature Sensors

The MAX1668/MAX1805/MAX1989 are precise multichannel digital thermometers that report the temperature of all remote sensors and their own packages.

The remote sensors are diode-connected transistors *typically low-cost, easily mounted 2N3904 NPN types *that replace conventional thermis
