ZSSC4169DE1B-APC

Overview

The ZSSC4169DE1B-APC is an automotive-grade sensor signal conditioner from the Renesas ZSSC416x series, designed for high-precision amplification and calibration of differential bridge sensors. It features a maximum analog gain range of 200, accommodating various resistive bridge and voltage source inputs. Digital compensation for offset, sensitivity, temperature drift, and nonlinearity is executed by an integrated 16-bit RISC microcontroller. The device supports SENT and I2C digital output interfaces, operates on a 4.75 V to 5.25 V supply, and functions within a -40°C to +150°C temperature range in a 24-pin VFQFPN package.

Feature Summary

• Integrated 16-bit RISC microcontroller performs digital compensation for offset, sensitivity, temperature drift, and nonlinearity.
• Supports differential bridge, thermocouple, and voltage input types with adjustable analog gain.
• Provides SENT or I2C digital output interfaces for direct connection to vehicle networks.
• Automotive qualification compliant with AEC-Q100 standards for reliability.

Applications

• Automotive pressure sensors
• Automotive temperature sensors
• Automotive acceleration sensors

Procurement Notes

Verify the specific suffix DE1B-APC against official Renesas documentation to confirm wafer-level packaging status and availability. Confirm that the intended application aligns with the automotive qualification requirements. Ensure compatibility with the ZSSC4169 evaluation tools if development support is required. Check for any obsolescence notices or lifecycle changes directly from the manufacturer.

Selection Notes

Select this component when high-precision conditioning of differential bridge sensors is required in automotive environments. The integrated digital calibration reduces external component count and improves system accuracy. Ensure the interface requirement matches either SENT or I2C protocols. Verify that the operating temperature range meets the specific application constraints.

Part Context

This part belongs to the ZSSC416x family of sensor signal conditioners. It shares core functionality with variants like ZSSC4169DE4W but differs in packaging and suffix specifications. The family is designed for automotive applications requiring robust signal integrity and digital calibration capabilities.

Replacement Considerations

Direct substitutes within the same family include ZSSC4169DE4W and ZSSC4169DE4R-APC. Verify pinout and packaging compatibility before substitution. Consult official datasheets for any functional differences between suffixes.
