DESCRIPTION
The XTR110 is a precision voltage-to-current con-
verter designed for analog signal transmission. It ac-
cepts inputs of 0 to 5V or 0 to 10V and can be
connected for outputs of 4 to 20mA, 0 to 20mA, 5 to
25mA and many other commonly used ranges.
A precision on-chip metal film resistor network pro-
vides input scaling and current offsetting. An internal
10V voltage reference can be used to drive external
circuitry.
The XTR110 is available in 16-pin plastic DIP, ce-
ramic DIP and SOL-16 surface-mount packages. Com-
mercial and industrial temperature range models are
available.

APPLICATIONS INFORMATION
Figure 1 shows the basic connections required for 0 to 10V
input and 4 to 20mA output. Other input voltage and output
current ranges require changes in connections of pins 3, 4, 5,
9 and 10 as shown in the table of Figure 1.
The complete transfer function of the XTR110 is:

RSPAN
(1)
RSPAN is the internal 50Ω resistor, R9, when connected as
shown in Figure 1. An external RSPAN can be connected for
different output current ranges as described later.
EXTERNAL TRANSISTOR
An external pass transistor, QEXT, is required as shown in
Figure 1. This transistor conducts the output signal current.
A P-channel MOSFET transistor is recommended. It must
have a voltage rating equal or greater than the maximum
power supply voltage. Various recommended types are shown
in Table I.
