LM75A Digital temperature sensor and thermal Watchdog

LM75A Digital temperature sensor and thermal Watchdog

The LM75A is a temperature-to-digital converter using an on-chip band-gap temperature sensor and Sigma-delta A-to-D conversion technique. The device is also a thermal detector providing an over-temp detection output. The LM75A contains a number of data registers: Configuration register (Conf) to sto.
