ADG708BRUZ analog switch module

This design is an eight-select one analog switch module based on ADG708BRUZ-REEL7 ([Mall No. C35325](https://item.szlcsc.com/36298.html)).

# Instructions for use:

All pins are out, and the onboard dip switches and LEDs are for independent testing. When you need to use the onboard LED to indicate the status, short-circuit the T1 test pad and use a jumper cap to short-circuit the VCC and D of J5. When not using a negative power supply, use a jumper cap to short-circuit J3's GND and VSS.

After completing the test, if you need to use the analog switch independently, disconnect the T1 test pad.


# The on-resistance test

VCC is 5.0V, VSS and GND are short-circuited, the channel on-resistance is about 2.7 to 3.1 ohms, and the cut-off resistance is measured using the LCSC530+ 200MΩ range and shows an open circuit.

VCC is 3.3V, VSS is shorted to GND, and the channel on-resistance is about 2.8 to 3.1 ohms.

VCC is 1.8V, VSS is short-circuited to GND, and the channel on-resistance is about 13 ohms.
