1) The systematic temperature dependence is appr. + 7 mV / °C
2) The systematic temperature dependence is appr. -0.3 % / °C
3) The systematic temperature dependence is appr. +0.1 %/ °C
4) With VDD = 3.3 V, the IT output current in reverse polarity is limited to typically 700 A; thus, the DC current regulation
5) The offset (
6) The systematic temperature dependence is appr. -0.1 %/ °C

loop operates correctly only up to the corresponding line current value of 35 mA. In all other cases, IT is linear within the
full line current range
