Only the MSB 11 bits (1 sign + 10 temperature * bits) are meaningful; the LSB 5 bits are to be discarded. * See the datasheet. * * Further, each bit represents 0.25 degrees Celsius; so, multiply * by 0.25. Also multiply by 1000 to represent in millidegrees * Celsius. * So it's equivalent to multiplying by 0.25 * 1000 = 250. * * LM74 and TMP121/TMP122/TMP123/TMP124: * 13 bits of 2's complement data, discard LSB 3 bits, * resolution 0.0625 degrees celsius. * * LM71: * 14 bits of 2's complement data, discard LSB 2 bits, * resolution 0.0312 degrees celsius. * * TMP125: * MSB/D15 is a leading zero. D14 is the sign-bit. This is * followed by 9 temperature bits (D13..D5) in 2's complement * data format with a resolution of 0.25 degrees celsius per unit. * LSB 5 bits (D4..D0) share the same value as D5 and get discarded.
