How is acquisition timing distributed across MUXed inputs in sequencer mode with OSR = 4 on the AD7386-4? Does the timing sequence follow the pattern: "0, 1, 0, 1, 0, 1, 0, 1" or "0, 0, 0, 0, 1, 1, 1, 1"?

Assuming you are using AD738x-4 in the normal oversampling mode, at OSR=4. When in sequencer mode, the throughput rate will be much slower. And also in normal averaging, the throughput rate will also gets slower as the OSR increases as it needs more samples to average. With regards to the algorithm, when in sequencer mode, the device gets to sample at Channel 0, acquires and convert samples 4x, then on the next CS low or next conversion cycles, it clocks out conversion result of CH0 and simultaneously start conversion of Channel 1. Then this process repeats back to channel 1 again. Hence this makes sense: 0,0,0,0,1,1,1,1. Please refer to the ADC TRANSFER FUNCTION in the AD7386-4/AD7387-4/AD7388-4 datasheet (Rev.0) (Page 17 of 36) for more details.
