ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the datasheet table. The suffix 'V' indicates approval under UL, CSA, and DIN EN 60747-5-5 safety standards, whereas 'C' denotes standard UL and CSA approval only. Confirm the packing style matches the required quantity, as embossed tape options are available in 2000-piece reels or 20-piece cut tapes.

ADCs/DACs - Special Purpose Selection Notes

Ensure the supply voltage on both sides falls within the recommended operating conditions: VDD1 between 4.5 V and 5.5 V, and VDD2 between 3.0 V and 5.5 V. The differential input voltage must remain within the accurate linear range of -200 mV to +200 mV. Connect VIN- to GND1 for optimal performance and avoid voltages exceeding 2.5 V on this pin to prevent activation of internal test modes.

ADCs/DACs - Special Purpose Part Context

This component belongs to the RV1S9353A series of optically isolated Delta-Sigma modulators manufactured by Renesas Electronics. It utilizes gallium arsenide technology for its optical coupling mechanism. The device is designed to replace traditional analog isolators by providing high-resolution digital output directly across the isolation barrier.
