Low-Cost, SOT23, Voltage-Output,

High-Side Current-Sense Amplifier

_______________________________________________________________________________________

Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.

Note 2: Guaranteed by Total Output Voltage Error Test.

Note 3: Total OUT Voltage Error is the sum of gain and offset voltage errors.

Note 4: +6.25mV = 1/16 of +100mV full-scale voltage.

Note 5: VSENSE such that output stage is in saturation.

Note 6: The device does not experience phase reversal when overdriven.
