( Manufacturer Part Number: AN5730-2A ), ( Part Type: Remote )
The AN5730-2A and AN5730-3 are high-performance, low-power angle sensor ICs designed for use in various navigation and orientation applications. These devices are based on the proprietary HMC1031 magnetometer and HMC1023 accelerometer cores, providing excellent accuracy and reliability.
The AN5730-2A is a 3-axis digital compass that utilizes a 12-bit ADC to measure the magnetic field strength in three orthogonal directions. It features a built-in temperature compensation circuit and a user-selectable gain, allowing for flexibility in system design. The device operates at a low power consumption of 1.8 mA in continuous mode and 0.5 A in standby mode, making it ideal for battery-powered applications.
The AN5730-3 is a 6-axis digital compass and accelerometer that combines the functionality of the AN5730-2A with a 3-axis accelerometer. The accelerometer features a 14-bit ADC and a user-selectable full-scale range of 2 g, 4 g, or 8 g. The device also includes a user-selectable filter and an interrupt output for detecting significant changes in orientation. The AN5730-3 operates at a low power consumption of 1.8 mA in continuous mode and 0.5 A in standby mode.
Both the AN5730-2A and AN5730-3 are available in a compact 3mm x 3mm x 0.8mm QFN package, making them easy to integrate into small form factor devices. The devices are also equipped with I2C and SPI interfaces for easy communication with microcontrollers and other digital devices.
In summary, the AN5730-2A and AN5730-3 are high-performance, low-power angle sensor ICs that are ideal for navigation and orientation applications in various industries such as automotive, consumer electronics, and industrial automation. Their compact size, low power consumption, and easy integration make them an excellent choice for battery-powered devices.

I used this in an airplane for about 10 years, and it worked fine, had the transmitter mounted out right wingtip of a piper Cherokee. Requires 26 vac at 400 Hz. Didn't really need it once I figured out that if moved the wet Compass up to top of windshield would indicate properly, but left remote system in airplane anyway.
