Digital and Analog Compasses
1490 Digital Compass
The 1490 Digital Compass is a solid state
device capable of detecting the earth's weak magnetic
field. It can distinguish between the four
cardinal points and also the intermediate directions
(NE, NW, SE, SW). The sensor is dampened
to approximate the speed of a liquid filled compass.
It takes 2.5 seconds for it to respond to a 90
degree displacement. The device is sensitive
to tilt, and any tilt greater than 12 degrees
will create directional errors.

1525 Analog Compass
The 1525 Analog Compass measures the direction
of the horizontal component of the earths
field. For practical purposes up to a 12
degree tilt, as with any compass is acceptable.
The output closely resembles a sine-cosine set
of curves which cross at approximately 2.5 volts
and peak at around 2.88 volts and floor at 2.12
volts. Each output will drive up to 4 mA.
