LM94 Datasheet (National Semiconductor) - TruTherm Hardware Monitor

LM94, TruTherm Hardware Monitor

The LM94 hardware monitor has a two wire digital interface compatible with SMBus 2.0.

Using a Σ∆ ADC, the LM94 measures the temperature of four remote diode connected transistors as well as its own die and 16 power supply voltages.

The LM94 has new TruTherm technology that supports precision thermal
