Note 1: Guaranteed by design.
Note 2: Total unadjusted errors are for the entire gain drive channel including the 8- and 10-bit DACs and the gate driver. They are
all measured at the GATE1 and GATE2 outputs. Offset removal refers to presetting the drain current after a room tempera-
ture calibration by the user. This effectively removes the channel offset.
Note 3: During power-on reset, the output safe switch is closed. The output safe switch opens once both AV DD and DV DD supply
voltages are established.
Note 4: Integral nonlinearity is the deviation of the analog value at any code from its theoretical value after the gain and offset errors
have been removed.
Note 5: Offset nulled.
Note 6: Absolute range for analog inputs is from 0 to AV DD .
Note 7: The MAX1385/MAX1386 and external sensor are at the same temperature. External sensor measurement error is tested with
a diode-connected 2N3904.
Note 8: The drive current ratio is defined as the large drive current divided by the small drive current in a temperature measure-
ment. See the Temperature Measurements section for further details.
Note 9: Guaranteed monotonicity. Accuracy might be degraded at lower V REFDAC .
Note 10: Supply current limits are valid only when digital inputs are at DV DD or DGND. Timing specifications are only guaranteed
when inputs are driven rail-to-rail.
Note 11: Shutdown supply currents are typically 0.1μA. Maximum specification is limited by automated test equipment.
Note 12: All timing specifications referred to V IH or V IL levels.
Note 13: A master device must provide a hold time of at least 300ns for the SDA signal (referred to V IL of SCL) to bridge the unde-
fined region of SCL’s falling edge.
Note 14: C b = total capacitance of one bus line in pF; t R and t F are measured between 0.3 x DV DD and 0.7 x DV DD .
Note 15: For a device operating in an I 2 C-compatible system.
Note 16: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
Note 17: A device must provide a data hold time to bridge the undefined part between V IH and V IL of the falling edge of the SCL signal.
An input circuit with a threshold as low as possible for the falling edge of the SCL signal minimizes this hold time.
Note 18: Cb = total capacitance of one bus line in pF. For bus loads between 100pF and 400pF, the timing parameters should be
linearly interpolated.
