1. Unless otherwise specified, the test conditions are Tamb = 25°C, VCC = 12 V, Vsense = Vp-Vm = 50 mV, Vm = 12 V, no load on

Out.

2. See Output voltage drift versus temperature on page 13 for the definition.

3. Output voltage accuracy is the difference with the expected theoretical output voltage Vout-th = Av*Vsense. See Output

voltage accuracy on page 14 for a more detailed definition.
