Notes:
General Note: Typical values represent the
mean value of all characterization units at
the nominal operating conditions. Typical
drift specifications are determined by
calculating the rate of change of the speci-
fied parameter versus the drift parameter
(at nominal operating conditions) for each
characterization unit, and then averaging
the individual unit rates. The correspond-
ing drift figures are normalized to the
nominal operating conditions and show
how much drift occurs as the particular
drift parameter is varied from its nominal
value, with all other parameters held at
their nominal operating values. Figures
show the mean drift of all characterization
units as a group, as well as the
± 2-sigma
statistical limits. Note that the typical drift
specifications in the tables below may
differ from the slopes of the mean curves
shown in the corresponding figures.
1. HP recommends the use of non-
chlorine activated fluxes.
2. The HCPL-7800 will operate properly
at ambient temperatures up to 100
°C
but may not meet published specifi-
cations under these conditions.
3. DC performance can be best
maintained by keeping VDD1 and VDD2
as close as possible to 5 V. See
application section for circuit
recommendations.
4. HP recommends operation with VIN-
= 0 V (tied to GND1). Limiting VIN+
to 100 mV will improve DC
nonlinearity and nonlinearity drift. If
VIN- is brought above 800 mV with
respect to GND1, an internal test
mode may be activated. This test mode
is not intended for customer use.
5. Although, statistically, the average
difference in the output resistance of
pins 6 and 7 is near zero, the standard
deviation of the difference is 1.3
due to normal process variations.
Consequently, keeping the output
current below 1 mA will ensure the
best offset performance.
6. Data sheet value is the average change
in offset voltage versus temperature at
TA =25°C, with all other parameters
held constant. This value is expressed
as the change in offset voltage per
°C
change in temperature.
7. Data sheet value is the average
magnitude of the change in offset
voltage versus temperature at
TA =25°C, with all other parameters
held constant. This value is expressed
as the change in magnitude per
°C
change in temperature.
8. Data sheet value is the average change
in offset voltage versus input supply
voltage at VDD1 = 5 V, with all other
parameters held constant. This value
is expressed as the change in offset
voltage per volt change of the input
supply voltage.
9. Data sheet value is the average change
in offset voltage versus output supply
voltage at VDD2 = 5 V, with all other
parameters held constant. This value
is expressed as the change in offset
voltage per volt change of the output
supply voltage.
10. Gain is defined as the slope of the
best-fit line of differential output
voltage (VOUT+ - VOUT-) versus
differential input voltage (VIN+ -VIN-)
over the specified input range.
11. Data sheet value is the average change
in gain versus temperature at
TA =25°C, with all other parameters
held constant. This value is expressed
as the percentage change in gain per
°C change in temperature.
12. Data sheet value is the average
magnitude of the change in gain
versus temperature at TA =25°C, with
all other parameters held constant.
This value is expressed as the
percentage change in magnitude per
°C change in temperature.
13. Data sheet value is the average change
in gain versus input supply voltage at
VDD1 = 5 V, with all other parameters
held constant. This value is expressed
as the percentage change in gain per
volt change of the input supply
voltage.
14. Data sheet value is the average change
in gain versus output supply voltage at
VDD2 = 5 V, with all other parameters
held constant. This value is expressed
as the percentage change in gain per
volt change of the output supply
voltage.
15. Nonlinearity is defined as the maxi-
mum deviation of the output voltage
from the best-fit gain line (see Note
10), expressed as a percentage of the
full-scale differential output voltage
range. For example, an input range of
± 200 mV generates a full-scale differ-
ential output range of 3.2 V (
± 1.6 V);
a maximum output deviation of 6.4
mV would therefore correspond to a
nonlinearity of 0.2%.
16. Data sheet value is the average change
in nonlinearity versus temperature at
TA =25°C, with all other parameters
held constant. This value is expressed
as the number of percentage points
that the nonlinearity will change per
°C change in temperature. For
example, if the temperature is
increased from 25
°C to 35°C, the
nonlinearity typically will decrease by
0.01 percentage points (10
°C times
-0.001 % pts/
°C) from 0.2% to 0.19%.
17. Data sheet value is the average change
in nonlinearity versus input supply
voltage at VDD1 = 5 V, with all other
parameters held constant. This value
is expressed as the number of
percentage points that the nonlinearity
will change per volt change of the
input supply voltage.
18. Data sheet value is the average change
in nonlinearity versus output supply
voltage at VDD2 = 5 V, with all other
parameters held constant. This value
is expressed as the number of
percentage points that the nonlinearity
will change per volt change of the
output supply voltage.
19. NL100 is the nonlinearity specified over
an input voltage range of
± 100 mV.
20. Because of the switched-capacitor
nature of the input sigma-delta
converter, time-averaged values are
shown.
21. This parameter is defined as the ratio
of the differential signal gain (signal
applied differentially between pins 2
and 3) to the common-mode gain
(input pins tied together and the signal
applied to both inputs at the same
time), expressed in dB.
22. When the differential input signal
exceeds approximately 300 mV, the
outputs will limit at the typical values
shown.
23. The maximum specified input supply
current occurs when the differential
input voltage (VIN+ - VIN-) = 0 V. The
input supply current decreases
approximately 1.3 mA per 1 V
decrease in VDD1.
24. The maximum specified output supply
current occurs when the differential
input voltage (VIN+ -VIN-) = 200 mV,
the maximum recommended operating
input voltage. However, the output
supply current will continue to rise for
differential input voltages up to
approximately 300 mV, beyond which
the output supply current remains
constant.
