Hi, previously, I was using MAX14866 SPI controlled high voltage SPST analog switch.
This was nice but it was too expensive and it had excessive channels.
So I want to change to TI's SPST analog switch solution. Can I get a recommendation, please?
My requirements are
- USB 5V and 3.3V supply available, do not want a dual +-5V supply to control the switch (I'm using Arduino DUE - 3.3V ARM Cortex M3 chip).
- 6 or more channels (6 or more circuits to open/close)
- each switch circuits has to handle bipolar high voltage (-80V ~ 80V, -80mA ~ 80mA).
An amplified Op Amp output voltage will be connected to the switch and I'm trying to connect/disconnect the load.
- control open/close via SPI/I2C/GPIO (SPI preferred)
- SMD package preferred (but not Ball Grid types)
- unit price doesn't matter for now
Thanks for your help.
