4-20mA Current Loop Isolated IC (ISO 4-20mA Series

DESCRIPTION:
ISO 4-20mA Current Loop Isolation Interface IC provides signal receive
and transmittal on a single chip. The ceramic hermetic hybrid package
contains an electromagnetic coupled converter and current modulate.
The very low input equivalent impendence allows the input voltage up
to a ultra-wide range (7.5V-32V), so that it is able to meet the
requirements for no distortion in long-distance signal transmission
under the circumstance of no outside connecting power. The internal
ceramic PCB, printed impendence and new isolation technologies allow
the IC for the 3KVAC insulated voltage and meets the industrial level
for the extremely poor temperature, humidity and shaking conditions.

CHARACTERISTICS:

Low cost, small size, standard SIP12 package
Signal input/Output, 3000VAC isolated voltage
No external instrument needed for power supply
4-20mA high accuracy of current input/output (distortion<0.2%)
Industrial temperature(-45-+85 Ąć)
(7.5-32V) Wide range of input voltage
high linearity(Nonlinearity<0.2%)
Frequency response (Small signal bandwidth) 2KHZ (Io=20mA)
Low resistance (Up<2V)
