The ADXRS646 is a high-performance angular rate sensor (gyroscope) that provides excellent vibration immunity. Bias stability is a widely recognized figure of merit for high performance. The ADXRS646 features 12°/hr bias stability, 0.01°/√sec angle random walk, wide bandwidth, expandable measurement range (up to ±450°/sec), 10,000 g powered shock survivability, 6 V single-supply operation, -40°C to +105°C operation, digital command self-test, ultra-small and light (<0.15 cc, <0.5 gram), single-chip temperature sensor output, RoHS compliance, and other features.
The ADXRS646 is a high‑performance angular‑rate gyroscope offering excellent vibration immunity, low bias drift (12°/hr typical) and a selectable measurement range up to +300 °/sec. It operates from a single 6 V supply and includes a temperature‑compensated output and self‑test functions.
The handbook contains detailed specifications, functional block diagrams, pin‑out tables, typical performance graphs, vibration immunity data, absolute‑maximum ratings, and an ordering guide for the CBGA package options.
