Isolated Conversion from Digital to 4-to-20 mA

µP-Compatible 10-Bit DAC1423 Uses Loop or Independent Supply; Has Readback Capability, Can Operate Manually When Computer Is Down

The DAC1423 produces a 4-to-20ma output current in response to a 10-bit binary digital signal provided via a latched 10-bit counter. The data, which might represent the desired setting of an actuator, is normally latched from an 8- or 16-bit data bus, in response to a WRITE command. Read full article
