Product data sheet
7.4.2 Configuration register
7.4.3 Temperature register
read a register that is different from the one that has been recently read, the pointer byte
must be included. However, a write to the LM75A must always include the pointer byte in
the statement. The bus communication protocols are described in
At power-up, the Pointer value is equal to 0 and the Temp register is selected; users can
then read the Temp data without specifying the pointer byte.
The Configuration register (Conf) is a write/read register and contains an 8-bit
non-complement data byte that is used to configure the device for different operation
conditions.
Table 8.
Legend: * = default value.
The Temperature register (Temp) holds the digital result of temperature measurement or
monitor at the end of each analog-to-digital conversion. This register is read-only and
contains two 8-bit data bytes consisting of one Most Significant Byte (MSByte) and one
Least Significant Byte (LSByte). However, only 11 bits of those two bytes are used to store
the Temp data in 2’s complement format with the resolution of 0.125 C.
