Description

The FM75 contains a high-precision CMOS temperature

sensor, a Delta-Sigma analog-to-digital converter, and a

SMBus-compatible serial digital interface. Typical accu-

racy 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 is 9).

Thermal alarm output, over-limit signal (OS) 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, the OS is disabled.

Available in a surface mount SOIC-8 (SOP-8) package.
