Overview
The IIS328DQTR, produced by STMicroelectronics, is an ultralow-power, high-performance 3-axis linear accelerometer. This device is designed for industrial applications that require an extended temperature range and long lifespan. It features a digital serial interface compatible with both SPI and I²C protocols. The IIS328DQTR is housed in a small, quad, flat package, no-lead (QFPN) with a 4x4 mm footprint, aligning with the trend towards application miniaturization. It operates over a temperature range from -40°C to +105°C and includes advanced power-saving and smart sleep-to-wake-up functions.
