Description
Within the FM75 are: a high-precision CMOS temperature
sensor, a Delta-Sigma analog-to-digital converter and a
SMBus compatible serial digital interface. Typical accuracy
is ±2°C over the full temperature range of –40°C to 125°C
and to ±1°C over the range of 0°C to 100°C, with 9- to 12-bit
resolution. Default resolution is 9 bits.
Thermal Alarm output, OS (Over-limit Signal) supports
Interrupt and Comparator modes. OS is active, if the
user-programmable trip-temperature is exceeded. When
the temperature falls below the trip-temperature plus the
user-programmable hysteresis limit, OS is disabled.
Available packages are surface mount SOIC-8 (SOP-8) and
MSOP-8.
