AMA1469 is an advanced motion sensor by Avago Technologies. It is specifically designed for use in robotics, industrial control, personal mobility and guidance systems. Based on the optical sensing technology, AMA1469 offers two-dimensional angular rate or rotational motion measurement in 360° range. This versatile motion sensor was developed as a cost-effective solution for accurate motion control for hard and soft robotics.

The AMA1469 is housed in a small, rugged package and has a high tolerance for both temperature extremes and vibration. It is also designed to reduce cross-axis sensitivity. The AMA1469 sensor is composed of a dome shaped optical array and a lens package. It also includes a laser emitter, an optical encoder and photodetector. The laser emitter projects an optical pattern on the optical array which is then detected by an optical encoder.

The optical encoder uses a quadrature signal that enables the AMA1469 to detect motion in two-dimensional range. As the user moves the sensor, the optical encoder rotates the pattern and as it is requested by the user, the electronics examines the signal from the optical encoder. The optical encoder signal is then converted to data using the embedded DSP. This data includes the measurement of angular rate or rotational motion.

The AMA1469 has an accuracy of 0.2°/s with a resolution of 0.001°/s. It also has a low noise floor and offers a drift rate of 0.1°/s over its full operating temperature range. The accuracy and resolution of the AMA1469 remain consistent across the entire 360° range of motion. The response time for the sensor is 1 ms with a maximum sampling frequency of 1 kHz.

The AMA1469 also offers built-in temperature compensation and over-temperature shut-down to protect the electronics from extreme temperatures. Moreover, the sensor has a soft start feature which allows the user to rest the sensor and conserve power when not in use. The AMA1469 can be used with many types of motion control systems, from simple two-wheeler applications to more complex three-dimensional control systems.

The AMA1469 is well suited for a wide range of motion sensing applications. Its robust design and fast response time make it a great choice for mobile robotics, navigation systems, and safety monitoring systems. The AMA1469 is an effective solution for motion sensing that is reliable, accurate, and cost-effective.
