The DONE output signal is an optional interface line that enables chaining multiple devices together to increase channel count. Connect the DONE signal to the CS of the next chained data converter in the system to control the start and stop of the subsequent converter interface. The DONE signal transitions from high to low following the LSB being shifted out. The delay time from the SCLK falling edge shifting out the LSB to the high-to-low DONE transition is configured using the DNDLY[1:0] bits in the D_SYS_CFG register. See Figure 6 for details of the signals and timings of the DONE signal.
For single device operation, configure DONE in the following ways:
See the Multiple Device Configuration section for more information on using the DONE signal for multiple device chaining.
