2 Equipment

This section describes the equipment needed to evaluate the full performance of the DAC12DL3200 device.

2.1 Evaluation Board Feature Identification Summary

Figure 2-1

 shows the EVM features.

Note

The EVM does not have any power sequencing as the EVM was designed before this requirement
was added to the data sheet. TI recommends using power sequencing per the 

Power Supply

Recommendations
