Z-axis acceleration—with ±19-g
full-scale range and 51.4-mg/LSB
sensitivity. The programmable event recorder can be triggered internally,
providing continuously sampled data—or externally, based on two comparator
inputs. Each event captures acceleration data, as well as supply voltage,
temperature, and time. User-configurable functions include trigger
threshold, capture length, pretrigger data, data storage, sample rate, and
alarms. All data and commands are transmitted via an SPI-compatible serial
