Evaluation Module Overview
1 Evaluation Module Overview
1.1 Introduction
This user's guide describes the characteristics, operation, and recommended use cases of the DAC8811EVM.
This document provides examples and instructions on how to use the DAC8811EVM board and included
software. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous
with the DAC8811EVM. This document also includes a schematic, reference printed circuit board (PCB) layouts,
and a complete bill of materials (BOM).
1.2 Kit Contents
Table 1-1
details the contents of the EVM kit. Contact the TI Product Information Center at (972) 644-5580 if any
component is missing. Download the latest versions of the related software on the TI website, www.ti.com.
1.3 Specification
Figure 1-1
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.
