BMA422 Description

Short technical summary and product information.

The Bosch BMA422 is an ultra-small accelerometer with digital interfaces, designed for low-power consumer electronics applications. It measures acceleration in three perpendicular axes and fulfills Android N low-power accelerometer requirements.

Key technical specifications include programmable measurement ranges of ±2 g, ±4 g, ±8 g, and ±16 g, with a digital resolution of 12 bits. The noise density is typically 140 µg/√Hz, and programmable bandwidths range from 1.5 Hz to 1600 Hz. It operates with a supply voltage (VDD) between 1.62 V and 3.6 V, and an I/O supply voltage (VDDIO) between 1.2 V and 3.6 V.

This accelerometer features low-g acceleration and low-noise measurements, making it suitable for applications requiring precise motion detection. It includes embedded intelligence for power management, significant motion detection, and gesture recognition. The device is easy to integrate due to its small LGA package size of 2 x 2 x 0.95 mm³.

Operating within a temperature range of -40°C to +85°C, the BMA422 offers current consumption as low as 12 µA in low-power mode. It supports SPI and I2C digital interfaces and includes two digital interrupt pins for flexible system integration.
