DAC80516 Evaluation Module
Description
The
DAC80516EVM
is an easy-to-use platform to
evaluate the functionality and performance of the
DAC80516
device. The DAC80516EVM has optional
circuits and jumpers to configure the device for
different applications. The DAC80516 is installed on
the EVM.
The DAC80516 offers 16 low power, 16-bit, buffered
voltage-output DACs with a full-scale output of 2.5V or
5V. The devices include a 2.5V internal reference. The
DAC output range is programmable to 2.5V or 5V.
Getting 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.
