MLX90821LXG-DBA-100-SP

Pressure Sensors Transducers Overview

The MLX90821LXG-DBA-100-SP is a packaged, factory-calibrated integrated relative pressure sensor from Melexis. It delivers a SENT digital signal for differential pressure measurements ranging from -6 kPa to 26 kPa (-0.87 PSI to 3.77 PSI). The device features a 12-bit resolution and operates within a supply voltage range of 4.5 V to 5.5 V. Designed for surface-mount installation in a 16-SOIC package with exposed pads, it supports board mounting applications. The sensor functions reliably across an operating temperature range of -40°C to +150°C.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'SP' against the official Melexis datasheet to confirm packaging configuration and availability status. Ensure compatibility with MSL Level 3 handling requirements during assembly. Confirm that the SENT interface aligns with the host controller's digital input capabilities before finalizing procurement orders.

Pressure Sensors Transducers Selection Notes

Select this component when a digital SENT interface is required for differential pressure sensing between -6 kPa and 26 kPa. The 12-bit resolution and factory calibration simplify system design by reducing external calibration needs. Ensure the application environment stays within the specified -40°C to +150°C operational temperature limits for optimal accuracy.

Pressure Sensors Transducers Part Context

This part belongs to the MLX90821 series of board-mount pressure sensors. It is designed for automotive and industrial applications requiring robust, calibrated pressure sensing.
