LIS35DE

LIS35DE Description

The LIS35DE from STMicroelectronics is a digital 3-axis accelerometer designed for precision motion sensing in compact, power-sensitive applications. Operating within a 2.16V–3.6V supply range, it offers selectable full-scale acceleration ranges of ±2.3g or ±9.2g, with adjustable sensitivity (55 LSB/g at ±2.3g, 13 LSB/g at ±9.2g) and bandwidth (50Hz–200Hz).** Its I2C/SPI digital output ensures seamless integration with microcontrollers, while its surface-mount 14LGA package (MSL3) suits space-constrained designs. Though marked obsolete, it remains relevant for legacy systems requiring low-power, high-resolution motion detection.

LIS35DE Features

• Triaxial Digital Output: Measures acceleration across X, Y, Z axes with I2C/SPI interfaces for flexible communication.
• Selectable Sensitivity: Adjustable full-scale ranges (±2.3g or ±9.2g) optimize performance for varying dynamic conditions.
• Low-Power Operation: Ideal for battery-powered devices, with a 2.16V–3.6V operating range.
• Robust Design: ROHS3/REACH-compliant, ensuring environmental and regulatory adherence.
• Bandwidth Control: Programmable 50Hz–200Hz bandwidth for noise vs. responsiveness trade-offs.

LIS35DE Applications

The LIS35DE excels in:

• Consumer Electronics: Motion-activated UI, gaming controllers, and wearable devices.
• Industrial Monitoring: Vibration analysis, tilt sensing, and shock detection in machinery.
• IoT Edge Devices: Low-power motion triggers for smart sensors and asset trackers.
• Legacy System Upgrades: Replacement for obsolete accelerometers in medical or automotive subsystems.

Conclusion of LIS35DE

While discontinued, the LIS35DE offers a compelling blend of programmable sensitivity, digital interfacing, and compact form factor, making it a pragmatic choice for legacy designs or niche applications. Its triaxial precision, low-voltage operation, and selectable ranges cater to demanding motion-sensing needs, though newer alternatives may supersede it in active development. Engineers valuing proven reliability in constrained environments may still find it advantageous.
