ZSSC4161DE4R-APB

Overview

The ZSSC4161DE4R is an automotive-grade sensor signal conditioning IC from the Renesas ZSSC416x series. It provides a single-channel interface for differential sensors, operating within a supply voltage range of 4.75 V to 5.25 V. The device features an internal reference and delivers digital output via an I2C interface. Designed for robust performance in harsh environments, it supports a minimum operating temperature of -40°C and a maximum of +150°C. The component is housed in a 24-pin VFQFPN package (4x4 mm) and is supplied in tape and reel format.

Feature Summary

• Automotive-grade qualification for high-temperature reliability
• Single-channel differential input signal conditioning
• Integrated internal reference voltage source
• Digital output with standard I2C communication protocol

Applications

• Automotive sensor signal conditioning
• High-temperature industrial sensor interfaces
• IoT system sensor integration

Procurement Notes

Verify the specific suffix 'APB' against official Renesas documentation, as standard listings typically use 'DE4R'. Confirm that the ordering code matches the exact package and reel specifications required for your assembly process. Ensure compatibility with the 4.75 V to 5.25 V power supply requirements during design validation.

Selection Notes

Select this component when a single-channel, digitally interfaced solution is required for differential sensors in automotive or high-temperature industrial applications. The internal reference simplifies board design by eliminating external reference components. Verify that the I2C interface speed and address configuration meet the system controller's requirements.

Part Context

This part belongs to the ZSSC416x/ZSSC417x family of sensor signal conditioning ICs from Renesas Electronics. These devices are designed to complement Renesas MCUs by handling amplification, digitization, and sensor-specific correction. They support faster design cycles and reduced system costs in IoT and automotive sensing applications.

Replacement Considerations

Check for other members of the ZSSC416x series if pinout or channel count variations are needed. Verify functional equivalence with any direct substitutes, ensuring that interface protocols and electrical characteristics remain compatible with the existing design.
