DAC80502-01 Evaluation Module
Description
The
DAC80502-01EVM
is an easy-to-use platform
to evaluate the functionality and performance
of the
DAC80502
and
DAC80501
DAC80502-01EVM has optional circuits and jumpers
to configure the device for different applications. The
DAC80502 and DAC80501 are both installed on the
EVM.
The DAC80501 is a single-channel, buffered, low-
voltage-output digital-to-analog converter (DAC) in 16-
bit resolution. DAC80502 is a dual-channel, buffered,
low-voltage-output DAC in 16-bit resolution. The
devices provide unipolar output voltage up to 5V.
Get Started
1. Order the EVM.
2. Configure EVM jumpers.
3. Install the DAC805xxEVM GUI from ti.com.
4. Connect USB and external power supplies.
5. Launch the DAC805xxEVM GUI.
