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

DAC improves spectral performance, saves space and cost in wireless communications, software defined radio and test and measurement equipment

DALLAS, April 6 -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a 16-bit, 800-MSPS interpolating digital-to-analog converter (DAC), which provides 75 dBc third-order intermodulation distortion (IMD3) at 200 MHz. Offered in a 7-mm x 7-mm QFN package, the DAC3283 is also the smallest DAC in its class, saving valuable board space in wireless communications, software defined radio (SDR), test and measurement, and power amplifier linearization applications. 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. For more information and to order samples, visit http://www.ti.com/dac3283-pr.

  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.

  Tools, availability and packaging

The DAC3283 is available now in a 48-pin, 7-mm x 7-mm QFN package. Pricing is $26.95 in 1,000-unit quantities. The footprint-compatible DAC3282, a 625-MSPS DAC optimized for baseband and low-IF transmitters with 2x interpolation and sinc-correction filter, is available and priced at $24.95. TI also offers the DAC3282 and DAC3283 evaluation modules (EVMs), complete with a transceiver chain that includes a high-performance clock generator (CDCE62005) and the TRF370417 quadrature modulator. The DAC EVMs are fully compatible with TI's TSW3100 pattern generator module to provide rapid evaluation.
