ADXL78 is a single-axis high-g iMEMS accelerometer from Analog Devices. It has ±35 g, ±50 g or ±70 g output full-scale ranges and is suitable for applications such as vibration monitoring and control, and vehicle collision sensing.
The ADXL78 is a complete single‑axis accelerometer on a monolithic IC that provides signal‑conditioned voltage outputs. It offers selectable full‑scale ranges of ±35 g, ±50 g or ±70 g, a fully differential sensor structure for high EMI/RFI resistance, and a built‑in self‑test capability. The device operates from a 3.5 V to 6 V supply, consumes only 1.3 mA, and is packaged in a 5 mm × 5 mm × 2 mm 8‑terminal ceramic LCC.
Typical applications include vibration monitoring, vehicle collision sensing, and shock detection. The ADXL78 is qualified for automotive use, supports both Sn/Pb and lead‑free solder processes, and includes features such as power‑supply decoupling recommendations, a 2‑pole Bessel filter with 400 Hz cutoff, and a robust self‑test that verifies both mechanical and electrical sensor elements.
