Overview
The LIS2L06ALTR is a low-power, 2-axis linear capacitive accelerometer produced by STMicroelectronics. This device integrates a sensing element and an IC interface, enabling it to convert detected accelerations into analog signals. The accelerometer is designed using a proprietary surface micro-machining process, allowing for high sensitivity and accuracy. It operates within a wide supply voltage range of 2.4V to 5.25V and is guaranteed to function over an extended temperature range of -40°C to +85°C. The LIS2L06ALTR is packaged in an 8-LLGA (Land Grid Array) surface mount package, making it suitable for various applications requiring compact and reliable acceleration sensing.
