 Description
The DIA1411 is high-precision sensor chip for
temperature monitoring in automotive sub-systems.
The on-chip 12-bit analog-to-digital converter (ADC)
offers resolutions down to 0.0625°C. The device
offers a typical inaccuracy of ±0.25°C without external
component signal conditioning.
The DIA1411 is compatible with the System
Management Bus (SMBus) and Inter-Integrated
Circuit (I2C) communication protocol. The DIA1411
can change the SMbus (or I2C) address by the
r_e_s_is_t_a_nce of different pull-up resistors on
THERM/ADDR pin.
The DIA1411 can operate at ambient temperatures
from -40°C to 125°C and have programmable alarm
function.
 Applications
 Automotive ADAS system
 Automotive infotainment system
 Processor temperature monitoring
