The H3LIS200DL is a low-power high performance 3-axis linear accelerometer
belonging to the “nano” family, with digital I2C/SPI
serial interface standard output.
The device features ultra-low-power operational
modes that allow advanced power saving and
smart sleep-to-wakeup functions.
The H3LIS200DL has dynamically user selectable full scales of ±100g/±200g and is
capable of measuring accelerations with output
data rates from 0.5 Hz to 1 kHz.
The H3LIS200DL is available in a small thin
plastic land grid array package (LGA) and is
guaranteed to operate over an extended
temperature range from -40 °C to +85 °C.
The LIS331HH is an ultra low-power high performance high full-scale three axes linear accelerometer belonging to the “nano” family, with digital I2C/SPI serial interface standard output. The device features ultra low-power operational modes that allow advanced power saving and smart sleep to wake-up functions. The LIS331HH has dynamically user selectable full scales of ±6g/±12g/±24g and it is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz. The self-test capability allows the user to check the funct
The IIS2DLPC is an ultra-low-power high-performance
three-axis linear accelerometer with digital I²C/SPI
output interface which leverages on the robust and
mature manufacturing processes already used for the
production of micromachined accelerometers.
The IIS2DLPC has user-selectable full scales of
±2g/±4g/±8g/±16g and is capable of measuring
accelerations with output data rates from 1.6 Hz to
1600 Hz.
The LIS2DW12 is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “femto” family which leverages on the robust and mature manufacturing processes already used for the production of micromachined accelerometers. The LIS2DW12 has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1.6 Hz to 1600 Hz.
