MSA321
Package:
LGA-12(2x2)
Key Attributes
Model Number:
MSA321
Product Description
Product Overview
The MSA321 is a digital tri-axial accelerometer designed for consumer applications, offering I2C digital output. It features dynamically selectable full-scale ranges of 2g/4g/8g/16g and supports output data rates from 1Hz to 1000Hz. Housed in an ultra-small 2mm x 2mm LGA package with a height of 0.95mm, it operates reliably within a temperature range of -40C to +85C. The device provides factory-programmed offset and sensitivity, low power consumption, and is RoHS compliant.
