Component building blocks

Functional blocks for selection; device connections and component values depend on your design.

FUNCTION / 01

Rotor-position conversion

Convert resolver signals into digital position data for a control loop.

FUNCTION / 02

Isolated current and voltage sensing

Measure shunt-current or divided-voltage signals across an isolation boundary using the corresponding amplifier function.

FUNCTION / 03

Analog data acquisition

Digitize analog signals using the channel count, resolution, sample rate and interface recorded for each ADC.
