ELECTRICAL CHARACTERISTICS: JTAG INTERFACE
(VDD = 2.7V to 5.5V, TA = -40NC to +85NC, unless otherwise noted.) (Figure 2)
Note 1: All voltages are referenced to ground (VSS). Currents entering the IC are specified positive and currents exiting the IC are
negative.
Note 2: This value does not include current in SDA, SCL, and P6.0–P6.4.
Note 3: Guaranteed by design.
Note 4: ADCCLK = SYSCLK/16. This is following an initial startup time of approximately 80s.
Note 5: Base line accuracy of reference source + 0.25% introduced by the MAX31782.
Note 6: The voltage applied to the pins must not exceed their corresponding absolute maximum voltages.
Note 7: ADC has no missing codes.
Note 8: Minimum SCL frequency applies only when in I2C master mode.
Note 9: After this period, the first clock pulse can be generated.
Note 10: This device internally provides a hold time of at least 25ns for the SDA signal (referenced to the VIHMIN of the SCL signal)
to bridge the undefined region of the falling edge of SCL.
Note 11: CB—Total capacitance of one bus line in pF.
Note 12: Filters on SDA and SCL suppress noise spikes at the input buffers and delay the sampling instant.
