DESCRIPTION
The DAC290x-EVM is designed for ease of use in evaluat-
ing the DAC290x dual, high-speed Digital-to-Analog Con-
verter (DAC) family. This family consists of three 125MSPS
DACs: the 10-bit DAC2900, the 12-bit DAC2902, and the
14-bit DAC2904. Due to its flexible design, the user can
evaluate the converter with different clock configurations,
independent bias control, internal or external reference source,
and single- or dual-supply operation. The analog output of
the DAC290x DACs can be configured to drive a 50Ω
terminated cable using a single-ended, or 4:1 or 1:1 imped-
ance ratio transformer.
