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 ??)
>> (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)

APPLICATION:
>> Analog signal data acquisition and isolation
>> Isolated 4-20mA signal transmission
>> Industrial process signal isolation
>> Ground-loop elimination
>> No distortion in long distance signal transmission
>> Instrument signal acquisition
>> Electric supervision and medical application
>> Isolated safe bar
