The DAC8755 provides one chip design for 4-channel,16b, bipolar voltage and current with 10us settling time, with highly integrated output front-end including the DAC, the reference, the buffers, as well as the buck-boost stages to implement adaptive power for current output from a wide Vin single supply of 12-65V. Less Than 1-W, Quad-Channel, Analog Output Module With Adaptive Power Management is a reference design showing the powerful features of this device, while Quad-Channel Industrial Voltage and Current Output Driver (EMC/EMI Tested) is going into the details of passing the EMC/EMI tests for the design.

Figure 4-1 shows how this integrated DAC simplifies board design (only one channel is shown), still providing flexibility of software output configuration, and adaptive power management.

When only voltage output is required, DAC81404 offers wide range of resolution and channel count to choose from. With integrated reference and 12us settling time, DAC81404 is able to cover the highest voltage AOUT demands. The DAC814xx family is capable of high voltage output up to ±20V or unipolar 40V needed for special applications. The 4-channel device DAC81404 provides voltage sense pins which helps maintaining output accuracy when protection devices are placed in series.
