Not much to say. Just a unidirectional toggle switch. The input is switched between two outputs. Voltage controlled. Status signaled with LED.
Specs and features
- Buffered in and output
- Status signaled by LED
- Runs on +/-15V and +/-12V
- Power consumption below 15mA each rail
The interesting point here is the overvoltage protection for the control voltage input. This is done with the MCP6002 rail to rail operational amplifier. He is powered between GND and +5V. So, no negative or positve voltage above +5V will go through it. The diode in the input is not neede for voltage protection. The diode protects the voltage source when it supplies a negative voltage. Without the diode the negative signal is loaded by the input of the MCP600x. The 1M resistors are there to provide a defined potential.
- You want to use the DG403 with the voltage range +/-15V. Check the datasheet. There are lower rated ones.
