ADIS16204 is a digital impact sensor and recorder from Analog Devices that is used for detecting crashes or impacts. The sensor has a 14-bit resolution and can detect ±70g and ±37g impacts. It can also record impact events. The sensor also has programmable sensitivity and bias, programmable sample rate, programmable condition monitoring alarms, auxiliary digital I/O, digitally activated self-test, embedded temperature sensor, programmable power management and SPI compatible serial interface.
The ADIS16204 is a fully‑contained programmable high‑g digital impact sensor that provides dual‑axis acceleration, RSS output, temperature sensing, and auxiliary ADC/DAC functions via an SPI‑compatible serial interface. It offers programmable event recording, configurable alarms, and power‑management modes such as low‑power and shutdown.
The document includes detailed specifications (full‑scale range, sensitivity, temperature range, power supply), timing diagrams for SPI communication, absolute maximum ratings, pin descriptions, recommended pad geometry, and typical performance characteristics to aid designers in integrating the sensor into their systems.
