The integrated temperature sensor allows compensation of bias drift over temperature, a practical concern when the gyro shares a PCB with heat-generating power stages. The 5.75 V supply rail is a single-point fit: the gyro needs a clean analog rail, not a 3.3 V or 5.0 V digital supply. Budget a low-noise LDO for this rail if the system's main supply is noisier than a few millivolts. The analog voltage output at 9 mV/°/s means a ±250°/s full-scale swing produces ±2.25 V around the zero-rate voltage — check that your ADC input range covers that span with headroom. The bandwidth spec of 1 kHz is the mechanical sensor bandwidth, not an electrical filter pole. For most rate-control loops this is adequate; if you need a narrower noise bandwidth, an external low-pass filter on the output pin is straightforward. The 4 mA supply current is modest — the gyro won't dominate the system power budget, but it does set a floor for the LDO's dropout headroom.","metaTitle":"ADXRS646BBGZ Yaw Rate Gyroscope, ±250°/s, 9 mV/°/s, Active","metaDescription":"ADXRS646BBGZ Z-axis (yaw) gyroscope from Analog Devices. ±250°/s range, 9 mV/°/s sensitivity, 5.75 V supply, -40°C to 105°C.
