SLAS535F September 2007 – October 2018 DAC5652A
The current outputs of the DAC5652A allow for a variety of configurations. As mentioned previously, utilizing the converter’s differential outputs yield the best dynamic performance. Such a differential output circuit may consist of an RF transformer or a differential amplifier configuration. The transformer configuration is ideal for most applications with ac coupling, while op amps are suitable for a dc-coupled configuration.
The single-ended configuration may be considered for applications requiring a unipolar output voltage. Connecting a resistor from either one of the outputs to ground converts the output current into a ground-referenced voltage signal. To improve on the dc linearity by maintaining a virtual ground, an I-to-V or op-amp configuration may be considered.
