Frequently Asked Questions
What supply voltage range does LIS2DH support and which battery-powered systems does it fit?
The LIS2DH operates from 1.71 V to 3.6 V, covering both 1.8 V coin cell and 3.3 V lithium-ion battery systems without additional regulation. This range is ideal for wearables, IoT nodes, and asset trackers where direct battery connection without a voltage regulator reduces power consumption and BOM cost.
What is the physical size of LIS2DH and how does this benefit wearable PCB designs?
The LIS2DH measures only 2 mm x 2 mm x 1 mm in its LGA-14 package, making it one of the smallest 3-axis accelerometers available. This ultra-compact size is essential for thin wearable bands, hearing aids, and compact IoT form factors where board area and device height are tightly constrained.
Which interface does LIS2DH use to communicate with a microcontroller, and at what maximum clock speed?
The LIS2DH supports both I2C and SPI digital interfaces, with I2C operating at up to 400 kHz (Fast Mode) and SPI at higher speeds for lower-latency data readout. The digital output range of 0.18 V to 1.62 V is compatible with 1.8 V logic MCUs, simplifying direct connection to low-power embedded controllers in IoT and wearable designs.
