There is a variable idle time between packets. This idle time varies with the update rate setting in EEPROM.

Figure 3.8

Transmission of a Number of Data Packets

The table below shows the idle time between packets versus the update rate. This idle time can vary by nominal

+/-15% between parts and over a temperature range of -50 to 150ºC.

Transmissions from the IC occur at one of two speeds depending on the update rate programmed in EEPROM. If

the user chooses one of the two fastest update rates (1 ms or 5 ms) then the baud rate of the digital transmission

will be 32 kHz (minimum 26kHz). If, however, the user chooses one of the two slower update rates (25 ms or

125 ms), then the baud rate of the digital transmission will be 8 kHz (maximum 9.6kHz).

The total transmission time for both digital output configurations is shown in Table 3.3.
