TSW3070EVM: Amplifier Interface to Current Sink DAC -
Arbitrary Waveform Generator Demonstration
The TSW3070 is an evaluation module (EVM) that shows how to use an active interface with the current
sink output of the DAC5682Z. The EVM includes the DAC5682Z for digital-to-analog conversion, an
OPA695 to demonstrate an active interface implementation using a wide bandwidth operational amplifier
and a THS3091 and THS3095 to showcase an operational amplifier with large voltage swing. Also
included on board are a CDCM7005, VCXO and Reference for clock generation, and linear regulators for
voltage regulation. Communication to the EVM is accomplished via a USB interface and GUI software.
