 Description
The DIO1411 is high-precision sensor chip for
temperature monitoring in computer, server, and
industrial applications. 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 DIO1411 is compatible with the System
Management Bus (SMBus) and Inter-Integrated
Circuit (I2C) communication protocol. The DIO1411
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 DIO1411 can operate at ambient temperatures
from -40°C to 125°C and have programmable alarm
function.
