Dynamics

Frontends

Each analog input has a filter pipeline that improves data quality while accommodating bandwidth requirements for common applications.

Digital IIR filters are adapted internally to target a cutoff frequency of 0.4x the cycle rate up to a 4500Hz cycle rate.

Above 4500Hz cycle rate, the digital antialiasing filter is disabled and antialiasing relies on frontend analog cutoff.

Kind	Frontend Cutoff	Target Use-Cases
Board temperature	100Hz	- Cold-junction correction. - System health.
Bus voltage	No frontend	System health.
Bus current	No frontend	System health.
0-2.5V	3kHz	General-purpose
0-15V	3kHz	0-10V sensor inputs.
±35mV	1kHz	Low-noise measurement of small signals.
3-Wire Resistance	3kHz	- Pt100 RTD temperature. - 100-ohm strain gauges.
K-type Thermocouple	1kHz	Fast responses and high maximum temperature.
4-20mA	3kHz	- Pressure transducers. - Valve angle feedback.

Internal Samplerate Variation

The internal samplerate nominally targets 9kHz and adjusts to synchronize to a multiple of the cycle rate, and to protect margin to worst-case execution time.
