SBAS740B October 2015 – May 2020 ADS1118-Q1
PRODUCTION DATA.
The serial clock pin (SCLK) features a Schmitt-triggered input and is used to clock data on the DIN and DOUT/DRDY pins into and out of the ADS1118-Q1. Even though the input has hysteresis, keep SCLK as clean as possible to prevent glitches from accidentally shifting the data. To reset the serial interface, hold SCLK low for 30.8 ms, and the next SCLK pulse starts a new communication cycle. Use this time-out feature to recover communication when a serial interface transmission is interrupted. When the serial interface is idle, hold SCLK low.
