LIMIT (VOLTAGE MODE) USING CURRENT SOURCE (1mA) (CS)

The external current source is applied to the inverting input of the uncommitted amplifier which
is configured as a current-voltage converter.

CAUTION

Observe the following to avoid damage to the power supply. The external current source
output must be isolated from ground (floating output), or be powered from an a-c source that is
isolated from ground to avoid short-circuiting the internal sensing resistor.
