... Testing is performed using a single unit of one of the transistors listed in Table 6. D Note 6. Current into this pin will result in self-heating of the MIC384. Sink current should be minimized for best accuracy. Note 7. Guaranteed by design over the operating temperature range. Not 100% production tested. ...

... Each MIC384 will only respond to its own unique slave address, allowing up to eight MIC384’s to share a single bus. A match between the MIC384’s address and the address specified in the serial bit stream must be made to initiate communication. A0 should be tied directly to VDD or ground. See " ...

... Table 3 shows examples of the data format used by the MIC384 for temperatures. A/D Converter Timing Whenever the MIC384 is not in its low power shutdown mode, the internal A/D converter (ADC) attempts to make continuous conversions unless interrupted by a bus transaction access- ing the MIC384. ...

... Interrupt Generation Assuming the MIC384 is in interrupt mode and interrupts are enabled, there are seven different conditions that will cause the MIC384 to set one of the status bits, S0, S1, or MIC384 S2, in CONFIG and assert its /INT output. These conditions are listed in Table 5. When a temperature event occurs, the corresponding status bit will be set in CONFIG ...

... Filter capacitor selection It is sometimes desirable to use a filter capacitor between the T1 and/or T2 pins and the GND pin of the MIC384. The use of these capacitors is recommended in environments with a lot of high frequency noise (such as digital switching noise long wires are used to attach to the remote di- odes ...
