Serial Clock Input (SCLK)
The serial clock input is provided with hysteresis to minimize
false triggering. Nevertheless, care should be taken to ensure
reliable clocking.
Filter Settling Time and ADC Latency
Whenever the analog signal into the ISL26132, ISL26134
converters is changed, the effects of the digital filter must be
taken into account. The filter takes four data ready periods for
the output code to fully reflect a new value at the analog input. If
the multiplexer control input is changed, the modulator and the
digital filter are reset, and the device uses four data ready
periods to fully settle to yield a digital code that accurately
represents the analog input. Therefore, from the time the control
inputs for the multiplexer are changed until the SDO/RDY goes
low, four data ready periods will elapse. The settling time delay
after a multiplexer channel change is listed in Table 8 for the
converter operating in continuous conversion mode.
