 Description
The DIO1408 is a high-precision sensor chip for
temperature monitoring in consumer, computer, and
SSD applications. The on-chip 12-bit analog-to-digital
converter (ADC) offers resolution of 0.0625°C.
The DIO1408 is compatible with the System
Management Bus (SMBus) and Inter-Integrated
Circuit (I2C) communication protocol. The DIO1408
can support SMBus alert function and up to four
configurable device addresses.
The DIO1408 can operate at ambient temperatures
of -40°C to 125°C and has programmable alarm
function.
