RTCU MX2 turbo Technical Manual V2.04

Analog Inputs

There are two analog inputs available on the unit.
The analog inputs are voltage inputs specified with an operating range of 0V to 10V DC. The
conversion resolution is 12 bit +/- 1.5% FSR @ 25 degrees ˚C.
By default the analog voltage is converted to a digital value with a resolution of 10-bit before being
presented to the application (0..1023). The application can change the resolution to the full 12 bit
(0..4095). Please consult the RTCU IDE documentation for further details.
The input signal is connected between AINx and AGND. AGND must be connected to the
reference of the connected equipment. Please be aware that deviations may occur, as the system is
very noise sensitive. Avoid long, unshielded wires and high current, fast changing signals routed
parallel to the analog signals.
The inputs are low-pass filtered, ESD- and transient protected.
