CONCLUSIONS
Lower Range:
From equation (10) it is observed that the
predominant error term is the input offset voltage (30
μ
V for
the B grade). This is of little consequence in many applica-
tions. V
OS
RTI
can, however, be nulled using the pot shown
in Figures 5 and 6. The result is an error of 0.06% of span
instead of 0.13% if span.
Upper Range:
From equation (11), the predominant errors
are I
OS
RTO
(6
μ
A), V
OS RTI
(30
μ
V), and I
B
(150nA), max, B
grade. Both I
OS
and V
OS
can be trimmed to zero; however,
the result is an error of 0.09% of span instead of 0.19% span.
RECOMMENDED HANDLING
PROCEDURES FOR INTEGRATED CIRCUITS
All semiconductor devices are vulnerable, in varying
degrees, to damage from the discharge of electrostatic
energy. Such damage can cause performance degradation or
failure, either immediate or latent. As a general practice, we
recommend the following handling procedures to reduce the
risk of electrostatic damage.
1. Remove the static-generating materials, such as untreated
plastic, from all areas that handle microcircuits.
2. Ground all operators, equipment, and work stations.
3. Transport and ship microcircuits, or products incorporat
ing microcircuits, in static-free, shielded containers.
4. Connect together all leads of each device by means of a
conductive material, when the device is not connected
into a circuit.
5. Control relative humidity to as high a value as practical
(50% recommended).
