ADT7302 Data Rate and Thermal Time Constant

Hi All,


My customer would like to know the maximum available data rate with ADT7302. The data sheet says conversion time is 1.2ms. And the devise clock is reset after every read or write operation for register and this cause the device to start a temperature conversion.

Does this mean the maximum data rate through interface is 1/ (1.2ms + register read time), around 80sps. Is this correct?


My customer also want to find device which has short thermal time constant. The thermal time constant of ADT7302 is 2 sec. Do you have any other recommendation which has minimum thermal time constant?


Best Regards,
