ZSC31150GEG2-R

Overview

The ZSC31150GEG2-R is a CMOS integrated circuit designed for the amplification and sensor-specific correction of bridge sensor signals. It accommodates virtually any resistive bridge sensor, such as piezoresistive and steel-membrane-based pressure sensors. The device features digital compensation for offset, sensitivity, temperature drift, and non-linearity via an internal 16-bit RISC microcontroller. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum operating current of 5.5 mA. The component supports I2C interfaces and is housed in a DFN-14 package. It is qualified under AEC-Q100 standards and functions across temperatures from -40°C to +150°C.

Feature Summary

• Provides digital compensation for sensor offset, sensitivity, temperature drift, and non-linearity using an internal 16-bit RISC microcontroller.
• Supports bi-directional digital interfaces including I2C and ZACwire for calibration coefficient programming into on-chip EEPROM.

Applications

• Automotive pressure sensors
• Force, torque, and acceleration sensors
• Angle, position, and revolution sensors
• Safety systems such as braking or steering

Procurement Notes

Verify the specific suffix GEG2-R confirms the reel packaging format and DFN-14 die variant when sourcing. Confirm AEC-Q100 qualification status aligns with project requirements. Ensure the supplier provides valid traceability documentation for automotive-grade components. Cross-reference the manufacturer part number against official Renesas databases to avoid counterfeit risks. Validate that the delivered units match the specified temperature range and interface capabilities.

Selection Notes

Select this component when interfacing with resistive bridge sensors requiring high-precision digital correction. The internal 16-bit resolution and adjustable ADC settings suit applications demanding accurate signal conditioning. Consider the DFN-14 package constraints for PCB layout. Verify that the I2C or ZACwire interface meets system communication needs. Ensure the operating temperature range covers the intended environmental conditions.

Part Context

The ZSC31150 series serves as a specialized sensor signal conditioner within Renesas Electronics' portfolio.
