4.2: Does the gain change if the internal LED light output
degrades with time?
No. The LED is used only to transmit a digital pattern.
Avago Technologies has accounted for LED degradation
in the design of the product to ensure long life.
5. POWER SUPPLIES AND START-UP
5.1: What are the output voltages before the input side
power supply is turned on?
V
is close to 1.29 V and V
is close to 3.80 V. This is
O+
O-
equivalent to the output response at the condition that
LED is completely off.
5.2: How long does the HCPL-7800(A) take to begin work-
ing properly after power-up?
Within 1 ms after V
and V
powered the device
DD1
DD2
starts to work. But it takes longer time for output to settle
down completely. In case of the offset measurement
while both inputs are tied to ground there is initially V
OS
adjustment (about 60 ms). The output completely settles
down in 100 ms after device powering up.
6. MISCELLANEOUS
6.1: How does the HCPL-7800(A) measure negative signals
with only a +5 V supply?
The inputs have a series resistor for protection against
large negative inputs. Normal signals are no more than
200 mV in amplitude. Such signals do not forward bias
any junctions sufficiently to interfere with accurate
operation of the switched capacitor input circuit.
