3.1.1 Theory of Operation

Figure 3-1 shows a simplified schematic of the DAC82002EVM board. By default, the DAC82002EVM features two OPA388 single-channel, low-noise operational amplifiers, and one OPA2328 dual-channel high-speed operational amplifier. Use jumpers J9 and J11 to select between unbuffered, low-noise, or high-speed output configurations for VOUTA and VOUTB. Adapters for 8-pin DIP packages are available that allow for the replacement of the default operational amplifiers with other options.
