NOTES: (1) An external transistor is used in the maufacturing test circuit for testing electrical specifications.
(2) This resistor is required for the 2N2222 with V

Current.
FIGURE 4. Power Supply Operating Range.
4. The maximum input signal level (e
INFS
) is 1V with R
S
=
∞
and proportionally less as R
S
decreases.
5. Always return the current references (pins 10 and 11) to
the output (pin 7) through an appropriate resistor. If the
references are not used for biasing or excitation, connect
them together to pin 7. Each reference must have between
0V and +(V
CC
– 4V) with respect to pin 7.
6. Always choose R
L
(including line resistance) so that the
voltage between pins 7 and 8 (+V
CC
) remains within the
11.6V to 40V range as the output changes between the
4-20mA range (see Figure 4).
7. It is recommended that a reverse polarity protection diode
(D
1
in Figure 1) be used. This will prevent damage to the
XTR101 caused by a momentary (e.g., transient) or long
term application of the wrong polarity of voltage between
pins 7 and 8.
