The input to output latency is dependent on the low-pass filter bandwidth. The shortest latency number can be achieved with the highest low-pass filter cut-off frequency. Also, the faster controller has a shorter latency. The following table provides a few reference points for the input to output latency.
|Low-pass corner||30° phase delay frequency||Latency|
|1 MHz||~55 kHz||~1.5 μs (Fast controller)|
|1 MHz||~5 kHz||~16.7 μs (Slow controller)|
|100 kHz||~16 kHz||~5.2 μs (Fast controller)|
|100 kHz||~4 kHz||~20 μs (Slow controller)|
