Two Channel Analogue Multiplexer with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12288
Indian Lab Suppliers supplies the Two Channel Analogue Multiplexer with Power Supply (Product ID: 12288) as part of its electronics engineering lab equipment range. It multiplexes two analogue signals onto one output using JFET switches.
Quick Answer
Each input passes through a JFET used as an analogue switch; when one JFET is on the other is held off, so the output carries the two signals in turn, and an IC 741 stage provides the combined output. Students feed two different waveforms from two function generators and view the inputs and the multiplexed output on a dual-trace 20 MHz CRO; the generators and CRO are not included. Internal supplies are ±15 V DC and −5 V DC (50 mA each).
