Notes:
ISO series isolation amplifier IC isolates and switches the analog signal pro rata, it is divided into two classifications: Internally powered and not powered.
Inside the not-powered IC contains current signal modulating circuit and signal coupling isolation & switching circuit. The very low input equivalent impendence allows the input voltage can be up to an 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 without any extra power supply.¡¡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.
ISO 4-20Ma series is very easy for application. No extra components are needed to realize the peRFormance of 4-20mA current loop isolation and signal switching of one in two out and two in two out.
The internally powered IC integrates a high isolated DC/DC Converter and high-performance linearity inter-coupler on a single chip. Except provides the power for the internal amplifying circuit, it also provides two-group isolated Positive-Negative power supply and two-group 5VDC nominal power supply for the outside signal input and output end, specially designed for the extending of outside circuits, like bridge circuit and small signal pre-amplifying circuit.
The IC contains 20KHz wide signal bandwidth that can isolate, modulate and switch 0~±10VDC bi-directional DC signal or 0~5VAC bi-directional AC signal. The IC is of small size, very easy to use. Only a few extra components are needed to realize the isolation and switching of analog signal¡¡(I/I, I/V, V/I, V/V).

Applications:
Analog signal data acquisition, Ground interference control, Signal long routed transmits, Equipment and sensor signal acquisition and switching, Electric and medical equipment safe bar.
