with option L
1 The minimum differential voltage DVio min between input and output increases linearly by 0 to 1 V between TA = 46°C and 71°C
(
TC = 70°C and 95°C)
External Input Circuitry
The sum of the lengths of the supply lines to the source or
to the nearest capacitor
≥100 F (a + b) should not exceed
5 m unless option L is fitted. This option is recommended in
order to prevent power line oscillations and reduce super-
imposed interference voltages. See also:
