Note 2:
The device operates properly with different supply voltages with equally different voltage swings.
Note 3:
Interpret errors expressed in terms of %FSR (percent of full-scale range) as a percentage of the end-point-to-end-point
range, i.e., for the ±64mA range, the full-scale range = 128mA, and a 1% error = 1.28mA.
Note 4:
Case must be maintained ±5°C for linearity specifications.
Note 5:
Tested in range C.
Note 6:
Current linearity specifications are maintained to within 700mV of the clamp voltages when the clamps are enabled.
Note 7:
Specified as the percent of full-scale range change at the output per volt change in the DUT voltage.
Note 8:
VCLLO_ and VCLHI_ should differ by at least 700mV.
Note 9:
The digital interface accepts +5V, +3.3V, and +2.5V CMOS logic levels. The voltage at VL adjusts the threshold.
Note 10: Guaranteed by design.
Note 11: Settling times are to 0.1% of FSR. CX_ = 60pF.
Note 12: All settling times are specified using a single compensation capacitor (CX_) across all current-sense resistors. Use an indi-
vidual capacitor across each sense resistor for better performance across all current ranges, particularly the lower ranges.
Note 13: The propagation delay time is only guaranteed over the force-voltage output range. Propagation delay is measured by
holding VSENSE_ steady and transitioning THMAX_ or THMIN_.
Note 14: Maximum serial clock frequency may diminish at VL < +3.3V.
AC ELECTRICAL CHARACTERISTICS (continued)
(VCC = +12V, VEE = -7V, VL = +3.3V, CCM_ = 120pF, CL = 100pF, TA = +25°C, unless otherwise noted. Specifications at TA = TMIN
and TA = TMAX are guaranteed by design and characterization. Typical values are at TA = +25°C, unless otherwise noted.) (Note 2)
