1.3 Specification

Figure 2-1 shows the block diagram of the DAC8811EVM board. By default, the DAC8811EVM connects to a local machine USB port through a USB-A to Micro-USB cable.

With the default jumper settings, the USB sources a 3.3-V supply for VDD and a 2.5-V reference for VREF through onboard low-dropout regulators (LDOs). The VDD and VREF supplies source power through J9 and J10, respectively. To use external supplies, remove the shunts connecting the jumpers, use banana jack connectors at J3 for GND, J4 for VDD, and use SMA connectors at J5 for VREF.

The OPA2828 is powered by external banana jack connectors at J1 and J2, for VCC and VSS respectively. The first amplifier converts the current output of the DAC8811 to a voltage, then the second amplifier gains the output to be a bipolar ±10-V output. The OPA2828 circuit can be configured to support other gain or shift values, and also other operational amplifiers.
