ZHCSEJ3B June 2015 – April 2020 ADS131E08S
PRODUCTION DATA.
Figure 55a shows a configuration with two ADS131E08s devices cascaded. Together, the devices create a system with 16 channels. DOUT, SCLK, and DIN are shared. Each device has its own chip select. When a device is not selected by the corresponding CS being driven to logic 1, the DOUT pin of this device is high-impedance. This structure allows the other device to take control of the DOUT bus. This configuration method is suitable for the majority of applications where extra I/O pins are available.
