1. Test conditions: pin 2 and 6 connected to GND, pin 4 and 5 connected to 1.25V, pin 3 connected to 200mV.

2. The current depends on the difference voltage between the negative and the positive inputs of the amplifier. If the voltage on the minus

input is 1mV higher than the positive amplifier, the sinking current at the output OUT will be increased by Gm*1mA.
