The DINSMORE INSTRUMENT 1490 is a digital compass sensor designed for navigation and orientation applications. It employs a solid-state Hall effect device, making it sensitive to the Earth's magnetic field. This sensor can display cardinal and intermediate directions, dampened to prevent over-swinging and with built-in hysteresis to avoid flutter.
Key electrical characteristics include an operating voltage of 5V and an open collector output capable of sinking up to 20 mA continuously or 25 mA intermittently. The device is sensitive to tilt, with errors occurring beyond 12 degrees.
This digital compass is suitable for use in PC-based navigation systems, mobile robotics, and microcontroller-based compass applications. Its solid-state nature and dampening provide reliable directional data for various electronic projects.

The 1490 operates at a nominal voltage of 5V, with leads labeled 1 connected to Vcc (+5V).
The 1490 provides an open collector output, equivalent to the open collector of an NPN transistor.
The maximum continuous output sink current is 20 mA.
The maximum intermittent output sink current is 25 mA.
The tilt sensitivity is 12 degrees maximum; any tilt greater than 12 degrees will create directional errors.
The 1490 uses a Hall Effect sensor and is solid-state.
