The ADXRS401 is a functionally complete and low cost angular rate sensor (gyroscope), integrated with all of the required electronics on one chip. It is manufactured using Analog Devices’ surface-micromachining technique, the same high volume BIMOS process used for high reliability. The ADXRS401 has a ±75°/s measurement accuracy, a Z-axis (yaw-rate) response, high vibration rejection over a wide frequency, 2000 g powered shock survivability, self-test on digital command, temperature sensor output, precision voltage reference output, absolute rate output for precision applications, 5 V single-supply operation, and is ultra small and light (< 0.15 cc, < 0.5 gram). It can be used for GPS navigation systems, image stabilization, inertial measurement units, and platform stabilization.
The ADXRS401 is a complete angular‑rate sensor on a 7 mm × 7 mm × 3 mm BGA package. It provides a voltage output proportional to yaw rate, a temperature‑compensated reference, and self‑test capability. The device operates from a 5 V single supply and is fabricated using Analog Devices' surface‑micromachining process.
The handbook includes detailed specifications, pin descriptions, typical performance graphs, theory of operation, bandwidth and range settings, temperature output calibration, and guidelines for using the sensor with a supply‑ratiometric ADC.
| Operating voltage | 4.75 V – 5.25 V |
|---|---|
| Quiescent supply current | 6 mA – 8 mA |
| Operating temperature range | ‑40 °C to +85 °C |
| Maximum shock acceleration (unpowered) | 2000 g |
The device operates from 4.75 V to 5.25 V.
Apply a logic high to ST1 to produce –0.800 V at RATEOUT, or to ST2 for +0.800 V; both can be activated simultaneously.
