Other Parts Discussed in Thread: TS5A3166-Q1, TINA-TI
Hi,
I'm building a circuit that includes the DAC8871. According to the datasheet page 16, it recommends that the CS (chip select) pin is connected to VDD trough a pull-up resistor.
I want to use a Raspberry Pi GPIO pin to control the CS. To ensure a proper startup I was thinking to connect the CS to VDD like stated in the datasheet and use an analog switch or a FET to control the CS pin.
I used a MOSFET before as a switch but never a analog switch like the TS5A3166-Q1. It should look like the circuit below. Unfortunately there is no TINA-TI SPICE model for the analog switch or similar products.
My question is will this work and how do I connect the pins of the analog switch to create the situation in the image.
Best regards,
Dukel
