MAX34406
Quad Current-Sense Amplifier
with Overcurrent Threshold Comparators
Note 1: All devices are 100% production tested at TA= +25NC. All temperature limits are guaranteed by design.
Note 2: VOUT1, VOUT2, VOUT3, VOUT4 = 0V. All open-drain outputs left disconnected.
Note 3: VOS is extrapolated from measurements for the gain-error test.
Note 4: Gain error is calculated by applying two values of VSENSE and calculating the error of the slope vs. the ideal: Gain = 100,
VSENSE is 5mV and 15mV.
Note 5: The device is stable for any external capacitance value.
ELECTRICAL CHARACTERISTICS (continued)
(VINx+ = VINx- = 12V, VSENSE = 0V, TA = -40NC to +85NC, unless otherwise noted. Typical values are TA = +25NC) (Note 1)x
