ZSSC4169DE1B

Overview

The ZSSC4169DE1B 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 14-bit resolution with a maximum sample rate of 1.3 kHz. The device operates on a supply voltage ranging from 4.75 V to 5.25 V and supports SENT and I2C digital output interfaces. It includes adjustable analog gain between 2.1 and 200, internal reference capabilities, and integrates a 16-bit RISC microcontroller for digital compensation of offset, sensitivity, temperature drift, and non-linearity.

Feature Summary

• Integrates a 16-bit RISC microcontroller for digital compensation of sensor errors including offset, sensitivity, temperature drift, and non-linearity.
• Provides adjustable analog gain ranging from 2.1 to 200 to accommodate various resistive bridge and voltage source sensor types.
• Supports dual digital output protocols, specifically SAE J2716 SENT and I2C, for flexible system integration.

Applications

• Automotive pressure sensing applications requiring AEC-Q100 qualification.
• Temperature measurement systems utilizing resistive bridge or thermocouple inputs.
• Industrial sensor interface modules needing high-precision signal conditioning.

Procurement Notes

Verify component authenticity through authorized Renesas distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging variants such as wafer or tape-and-reel configurations prior to ordering. Ensure compatibility with existing design specifications regarding interface protocols and power supply requirements.

Selection Notes

Select this model when both SENT and I2C outputs are required within a single channel configuration. Consider the 14-bit resolution and 1.3 kHz sampling rate against application latency needs. Evaluate the need for external versus internal reference sources based on system accuracy constraints and board space limitations.

Part Context

This component belongs to the ZSSC416x family of CMOS integrated circuits. It shares functional similarities with models like the ZSSC4169DE4W but differs in package type and manufacturing lot specifications. The DE1B suffix typically denotes a wafer-level configuration, distinct from the finished QFN packages found in other series variants.

Replacement Considerations

Direct substitutes include other members of the ZSSC416x series such as ZSSC4169DE4W or ZSSC4169DE4R. Verify pinout compatibility and software configuration differences before swapping. Alternative solutions may require redesigning the signal conditioning stage if interface protocols differ significantly.
