5/2/2012
Basic Specifications:
• The analog input can accept ±10 Volts.
• The input has an impedance of 20K ohms.
• Because of the nature of the design, the input will exhibit a 1.4V offset when not driven by an analog
source.
• Low source impedance is important for minimizing analog errors, 100 ohms or lower is recommended.
WARNING - The analog input must be used with care. It is not optically isolated and may
operate improperly or could be damaged when system grounds are not compatible.
