SA40012 – Single Axis CMOS Signal Conditioning Module
The SA40012 Single Axis CMOS Signal Conditioning Module is a DC input/output operated device, which operates off a
single ended supply, and provides a bipolar DC output. Specifically designed to interface directly with all Spectron Single Axis
Tilt Sensors, this low power consumption conditioner is ideal for battery driven applications. Featuring a PC board mountable
design, the module internally converts the DC input voltage into an AC excitation voltage for the sensor, and demodulates the
sensor output into a smooth amplified DC output voltage. Incorporating a proprietary signal processing algorithm, and an
external temperature compensation sensor (optional), normal measurement errors are severely reduced. The SA40012 also
features overload protection, and is 100% reliability tested to provide the highest quality available.

Temperature Compensation
- Temperature compensation of the assembly (module and sensor) can be accomplished using an external silicon
temperature sensor (KTY81-120) and a resistor (.RT., see wiring diagram for typical values). With this configuration, it is
possible to reduce the scale temperature coefficient error from a 0.3%/Co (nominal), to 0.03%/Co (nominal). Please see
wiring diagram for connection points.
