Electrical characteristics curves: current sense
amplifier
Unless otherwise specified, the test conditions for the following curves are:
• Tamb = 25 °C, VCC = 5 V, Vsense =Vp-Vm = 50 mV, Vm = 12 V.
• no load on Out pin.
• signal conditioning amplifier used as a buffer (pin A3 connected to pin Out and pin A1
connected to pin A2).
