PRODUCTION DATA
In industrial automation and process control applications, voltage and current analog output signals are used to operate control sources such as motors, solenoids and valve based actuators. The DAC provides a voltage output which is then used by control modules to drive industrial motors. Standard analog output ranges provided by these programmable logic control (PLC) systems include: 5 V, 10 V, ± 5 V and ± 12 V.
The end application and user requirements determine the appropriate output range, so software programmability of the output range is a desirable function in many system designs. Furthermore force-sense of the output voltage, capacitive load stability even with long cables at the DAC outputs, and smaller packages which enable multi-channel systems, are all important factors in these applications. Motor drive applications require a high precision voltage output to precisely control the motor movements in factory automations.
