TI delivers highest linearity, smallest dual, 16-bit, 800-MSPS interpolating DAC

Incorporating a single byte wide differential interface, the DAC3283 reduces data input pins by 50 percent, allowing designers to choose a lower-cost FPGA or ASIC to precede the DAC.



Key features and benefits of the DAC3283

· Single-carrier WCDMA adjacent channel leakage ratio (ACLR) of 81 dBc for 153 MHz IF offers improved spectral performance while simplifying system design.

· Selectable 2x/4x interpolator filters allow for lower reduced data input rates, while taking advantage of up to 800-MSPS DAC rates.

· I/Q phase and offset correction provides better performance when driving quadrature modulators (TRF370417) in demanding 3G, 4G and multi-carrier systems with transmit frequencies from 50 MHz to 6 GHz.

· Multi-DAC synchronization support reduces design complexity for diversity and smart antenna radios.
