Optically isolated delta-sigma modulator boosts accuracy

August 3, 2020  Stephen Law

RENESAS RV1S9353A optically isolated delta-sigma (ΔΣ) modulator delivers high accuracy compared to other 10MHz clock output optically isolated devices. Device includes a precision analog-to-digital converter with ENOB of 13.8 bits (typ) for converting an analog voltage input into a digital output one-bit data stream across the isolation barrier. Product connects directly to an RZ/T MPU and RX72M MCU, or other MPUs, MCUs, SoCs and FPGAs with a digital filter. Device is used in robotic arm controllers, as well as AC servo controllers and NC servo controllers employed in a range of smart factory equipment.
