8.2.3 Precision, Low-Noise, DAC Buffer

The OPA388 can be used for a precision DAC buffer, as shown in Figure 8-4, in conjunction with the DAC8830.

The OPA388 provides an ultra-low drift, precision output buffer for the DAC. A wide range of DAC codes can

be used in the linear region because the OPA388 employs zero-crossover technology. A precise reference is

essential for maximum accuracy because the DAC8830 is a 16-bit converter.
