If the voltage on Vctrl (the negative input of the amplifier) is higher than the positive amplifier input 
(Vref = 1.21 V), and it is increased by 1mV, the sinking current at the output OUT will be increased by
3.5 mA.

The internal Voltage Reference is set at 1.21 V (bandgap reference). The voltage control loop precision 
takes into account the cumulative effects of the internal voltage reference deviation as well as the input 
offset voltage of the transconductance operational amplifier. The internal Voltage Reference is fixed by 
bandgap, and trimmed to 0.5% accuracy at room temperature.

When the positive input at Ictrl is lower than -200 mV, and the voltage is decreased by 1mV, the sinking

The internal current sense threshold is set at -200 mV. The current control loop precision takes into

of the transconductance operational amplifier.
