If the output voltage is set to a higher value, Vi min will be proportionally increased. 2 Measured with a resistive and the max. admissible capacitive load. 3 Measured with a lead length of 0.1 m, leads twisted. Double-output models with both outputs in parallel. 70 /110 IMX7 models need an external capacitor at the input, e.g. 1 µF film or ceramic. 4 Source impedance according to ETS 300132-2, version 4.3, at Vi nom |
