7. Inputs Differential inputs offer the maximum noise rejection at the expense of half your total channel count For the best results shielded twisted pairs are a must The shield must connect at one end so that ground currents do not travel over the shield In low level voltage applications differential inputs reduce problems not only due to electrostatic and magnetic noise but due to cross talk and thermal errors One problem to consider with differential inputs is the bias current error The differential impedance is usually hundreds of megaohms With a very small bias current multiplied by this high input impedance the voltage produced is out of the common mode input range of the instrumentation amplifier You must provide an external resistor to return this bias current to the analog common of the data acquisition board This resistor is typically in the order of 1 kQto 100 kQ from the input low side to analog common Alternatively you can return the external common through a 10 Qto 100 kQresistor to analog common it cannot be 0 Q due to ground currents 75 Appendix A Analog Outputs The analog output channels on DT3000 Series boards have a resolution of 12 bits even though the accuracy may be less Data Translation ensures that the analog outputs do not break into a high frequency oscillation with high capacitance loads that occur with long cables Typically the analog outputs drive 1 000 pF without degradation and
8. bandwidth limit with higher capacitive loads The grounds of most boards are optimized for analog inputs at the expense of some logic or high frequency noise on the analog outputs This is because the analog and digital grounds of the board are connected at the ADC s input The analog outputs are brought out as a high and a low signal but the low side is the analog ground at the DAC s output buffer To remove the high frequency noise and smooth the glitch energy on the analog outputs you can install a 15 kHz RC filter on the output a 100 Q resistor in series with the output and a 0 1 uF capacitor between the output side of the 100 OQ resistor and output low 76 Using Your Own Screw Terminal Panel Digital Inputs and Counter Timer Inputs A To prevent damage when power is removed you must provide current limiting circuitry for TTL type input On high speed clock inputs a ground that is located in the connector next to the clock must be connected as a twisted pair with the high speed clock input 77 Appendix A Digital Outputs If you are using the high drive capability of a DT3000 Series board ensure that the load is returned to the digital ground provided in the connector next to the outputs If just eight of the digital outputs are switching 16 mA per output then 128 mA of current flows To minimize problems with ringing loading and EMI a 22 Qresistor is used in series with all digital outputs You must
