com The AS5043 provides a digital 10-bit as well as a programmable analog output that is directly proportional to the angle of a magnet, rotating over the chip.
The analog output can be configured in many ways, including user programmable angular range, adjustable output voltage range, voltage or current output, etc.
.
An internal voltage regulator allows operation of the AS5043 from 3.
3V or 5.
0V supplies.
360° contactless high resolution angular position encoding User programmable zero position Two 10-bit absolute outputs: Serial digital interface and Versatile analog output programmable angular range up to 360° programmable ratiometric output voltage range Failure detection mode for magnet field strength and loss of power supply Serial read-out of multiple interconnected AS5043 devices using daisy chain mode Mode input for optimizing noise vs.
speed Alignment mode for magnet placement guidance Wide temperature range: - 40°C to + 125°C Small package: SSOP 16 (5.
3mm x 6.
2mm) 4 Applications The AS5043 is ideal for applications with an angular travel range from a few degrees up to a full turn of 360°, such as Figure 1: Typical arrangement of AS5043 and magnet - 2 Benefits - Complete system-on-chip - Flexible system solution provides absolute output, both digital and analog - Angle measurement with software programmable range up to 360° - High reliability due to non-contact magnetic sensing - Ideal for applications in harsh environments - Robust system, tolerant to magnet misalignment, airgap variations, temperature variations a...
