JAJSAR0B March 2007 – October 2017 LM95214
PRODUCTION DATA.
The LM95214 takes approximately 190 ms to convert the Local Temperature, Remote Temperatures 1 through 4, and to update all of its registers. These conversions for each thermal diode are addressed in a round robin sequence. Only during the conversion process the busy bit (D7) in Status register (02h) is high. The conversion rate may be modified by the Conversion Rate bits found in the Configuration Register (03h). When the conversion rate is modified a delay is inserted between each round of conversions, the actual time for each round remains at 190 ms (typical all channels enabled). The time a round takes depends on the number of channels that are on. Different conversion rates will cause the LM95214 to draw different amounts of average supply current as shown in Figure 10. This curve assumes all the channels are on. If channels are turned off the average current will drop because the round robin time will decrease and the shutdown time will increase during each conversion interval.
