Electrical characteristics
Electrical characteristics
Unless otherwise specified, the electrical characteristics given in the following tables have
been measured under the following test conditions.
• 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).
