D converter and the D A converters this voltage must be accurate to the same degree Under normal operation the 453 Q resistor is not installed The reference zener diode in combination with the 100 Q resistor form a shunt regulator The 4 096 V reference voltage then feeds the A D converter the D A converters and the voltage divider composed of the 10 kQ and the 14 kQ resistors The voltage divider generates a second reference voltage of 1 707 V to feed the four op amps for the buffered A D converter inputs The reference voltage can be ratiometric rather than absolute This is done by removing the zener diode and installing the 453 Q resistor With this arrangement the reference voltages follow changes in the power supply voltages Vcc and V which is a filtered ver sion of Vcc This type of measurement circuit is preferred by some customers whose sen sors are powered from the Vcc supply and hence the outputs track Vcc A jumper on header JP3 allows the D A converters to be powered either from the 4 096 V reference factory default or from the analog supply V The D A converters use their power source also as the reference input so normally powering the D A converters from the more accurate 4 096 V reference is best However should a customer desire more dynamic range 0 5 V rather than 04 096 V the jumper across JP3 can be set to power the D A converters from V When powered from the V supply the outputs of the D A converters will a
