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 the entire line of SP5000 Series Dual 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 SA40015 also features overload protection, and is 100% reliability tested to provide the highest quality available.
