Overview
The RV1S2951ACCNS-1F0V#SC0 is an optically isolated delta-sigma modulator manufactured by Renesas Electronics. It integrates a high-accuracy analog-to-digital converter with a 20MHz internal clock to convert analog voltage inputs into one-bit data streams. The device provides an effective number of bits (ENOB) of 14 bits typical using a Sinc3 digital filter. Key electrical specifications include a minimum common-mode transient immunity (CMTI) of 50 kV/µs and a maximum creepage distance of 8mm. It operates within a supply voltage range of 4.5V to 5.5V for the primary side and 3V to 5.5V for the secondary side, supporting an ambient temperature range from -40°C to +125°C.
Feature Summary
- Integrates a high-accuracy A/D converter with a 20MHz internal clock for precise signal conversion.
- Provides high common-mode transient immunity to ensure reliable communication in noisy environments.
- Features long creepage distance for enhanced isolation safety standards compliance.
- Includes on-chip protection circuits and fault alarm outputs for system reliability.
Applications
- Motor current sensing in industrial instruments
- High-precision measurement in harsh noise environments
- Solar inverter systems
Procurement Notes
Verify the specific suffix codes against official Renesas documentation to confirm package type, tape-and-reel quantity, and environmental compliance status. Ensure the selected variant matches the required operating temperature range and isolation voltage ratings for the target application design.
Selection Notes
Select this component when high precision and robust isolation are required for analog signal transmission across potential barriers. Consider the 14-bit ENOB and 50 kV/µs CMTI for applications demanding accurate data acquisition in electrically noisy industrial settings.
Part Context
This part belongs to the RV1S series of optically isolated delta-sigma modulators designed for industrial applications. It replaces older discrete isolation solutions by integrating the ADC and isolation barrier on a single chip, reducing board space and improving system performance compared to standard optocouplers.
Replacement Considerations
Consult official Renesas replacement guides for direct pin-compatible alternatives or next-generation upgrades within the same isolation modulator family.
