Part Number: ADC128S102-SEP
From the datasheet of ADC128S102PWTSEP I can't find if DOUT pin is open-drain so multiple devices can share same SPI bus, or it can only be used as point-to-point with MCU. Can you advise? Thanks.

Hi Xiangguang,
DOUT pin is push-pull. Multiple devices can still share the same SPI bus, since DOUT becomes Hi-Z when ~CS is high. Each device will need to have its own ~CS line from the controller.
