Analog Switch
(Model : JAS-2)
Descriptions
이 JAS-2 는 두개의 Analog Signal을 Digital Input 입력에 의해 선택하여 출력할 수 있도록 하는
Analog Switch 이다.
그림에서 보는 것처럼 Switch 상하에 Terminal이 있고,
DIN Rail Mounting 방식이므로 편리하게 사용할 수 있다.
Digital Input Signal이 Open일 때, Analog Output은
Analog Input 1이 연결되고, Digital Input Signal이 Close
일 때, Analog Output은 Analog Input 2이 연결된다.
Red LED는 전원의 Status를 나타내고, Green LED는
Digital Input의 Status를 나타낸다.
Specifications
Analog Multiplexer, Digital Input Circuit, 전원회로 그리고 입출력 단자 등으로 구성된다.
The JAS-2 analog multiplexer is digitally-controlled analog switches having low ON impedance
and very low OFF leakage current. Control of analog signals up to 20VP-P can be achieved by
digital signal amplitudes of 4.5V to 20V (if VDD-VSS = 3V, a VDD-VEE of up to 13V can be controlled;
for VDD-VEE level differences above 13V, a VDD-VSS of at least 4.5V is required). For
example, if VDD = +4.5V, VSS = 0V, and VEE = -13.5V, analog signals from -13.5V to +4.5V can
be controlled by digital inputs of 0V to 5V. This multiplexer circuits dissipate extremely low quiescent
power over the full VDD-VSS and VDD-VEE supply-voltage ranges, independent of the logic
state of the control signals. When a logic “1” is present at the inhibit input terminal, all channels
are off.
