TDK InvenSense IAM-20381HT 3-axis accelerometer
The TDK InvenSense IAM-20381HT 3-axis accelerometer is a high-performance rail-to-rail grade 2 accelerometer with a 4096-byte FIFO. The accelerometer is fabricated using a CMOS-MEMS platform that integrates the MEMS wafer with supporting CMOS electronics via wafer-level bonding. The IAM-20381HT accelerometer includes ±2g, ±4g, ±8g, and ±16g user-programmable ranges, a programmable digital filter, an embedded temperature sensor, and an on-chip 16-bit ADC. The accelerometer is available in a 3mm x 3mm x 0.75mm 16-pin LGA package. The IAM-20381HT accelerometer features I2C and SPI serial interfaces, 10,000g shock resistance, and a Wake-on-Motion (WoM) interrupt that allows the application processor to operate at low power. The accelerometer is used for automotive alarms, telematics, tilt measurement, elevator door motion detection, and drive-by recording.
