3.1.1.2 Buffer Customization

The DAC82002EVM has three operational amplifier circuits that can be configured using 0-Ω resistors. All three circuits act as unity gain buffers with the default resistor placement. The following figure shows the 0-Ω resistors are the only resistors that are populated on the DAC82002EVM by default.

The three operational amplifiers can be replaced by the desired DIP-8 package. The inserted packages must follow the same pin mapping as the default operational amplifiers. Figure 3-3 shows the buffer DIP adapter connections.
