Figure 2. Conversion Time and Period

The serial data of the TMP121 and TMP123 consists of

12-bit plus sign temperature data followed by a

confirmation bit and two high impedance bits. Data is

transmitted in Binary Two’s Complement format. Figure 3

describes the output data of the TMP121 and TMP123.

Timing Diagrams

The TMP121 and TMP123 are SPI-compatible. Figure 4

and Figure 5 describe the various timing requirements,

with parameters defined in Table 3.
