The current can be provided. Such operation with an external resistor output models provide 10mA full scale allowing direct drive shunting the internal 1k resistor will reduce the already low of capacitive loads and transmission lines. All versions have a op amp offset drift precision reference and are active laser trimmed to specified . accuracy, thus no external adjustment pots or other compo- nents are required With 6 available units engineering trade-offs can be made be- tween resolution, speed, current or voltage output, and of course price. To facilitate this comparison major specifications are summarized in Table 1.
