FCC Warning
This equipment is intended for use in a laboratory test environment only. It gen-
erates, uses, and can radiate radio frequency energy and has not been tested
for compliance with the limits of computing devices pursuant to subpart J of
part 15 of FCC rules, which are designed to provide reasonable protection
against radio frequency interference. Operation of this equipment in other en-
vironments may cause interference with radio communications, in which case
the user at his own expense will be required to take whatever measures may
be required to correct this interference.

EVM IMPORTANT NOTICE
Texas Instruments (TI) provides the enclosed product(s) under the following conditions:
This evaluation kit being sold by TI is intended for use for ENGINEERING DEVELOPMENT OR
EVALUATION PURPOSES ONLY and is not considered by TI to be fit for commercial use. As
such, the goods being provided may not be complete in terms of required design-, marketing-,

EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of 0 V - VDD +0.3 V and the
output voltage range of ±10 V.
Exceeding the specified input range may cause unexpected operation and/or irreversible
damage to the EVM. If there are questions concerning the input range, please contact a TI field
representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or
possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to
connecting any load to the EVM output. If there is uncertainty as to the load specification, please
contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than
100°C. The EVM is designed to operate properly with certain components above 100°C as long
as the input and output ranges are maintained. These components include but are not limited
to linear regulators, switching transistors, pass transistors, and current sense resistors. These
types of devices can be identified using the EVM schematic located in the EVM User’s Guide.
When placing measurement probes near these devices during operation, please be aware that
these devices may be very warm to the touch.

1.1 Features
This EVM features the DAC7574, DAC6574, DAC5574, DAC7571, DAC6571,
DAC5571, and DAC8571 digital-to-analog converter (DAC). It provides a
quick and easy way to evaluate the functionality and performance of the
high-resolution as well as the low-resolution I2C-input DACs. Although the
EVM supports seven DAC types, only the selected DAC and its associated
