AD9144:  Quad, 16-Bit, 2.8 GSPS, TxDAC+® Digital-to-Analog Converter

Product Details

Product Status:Recommended for New Designs

The AD9144 is a quad, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a maximum sample rate of 2.8 GSPS, permitting a multicarrier generation up to the Nyquist frequency. The DAC outputs are optimized to interface seamlessly with the ADRF672x analog quadrature modulators (AQMs) from Analog Devices, Inc. An optional 3-wire or 4-wire serial port interface (SPI) provides for programming/readback of many internal parameters. Full-scale output current can be programmed over a typical range of 13.9 mA to 27.0 mA. The AD9144 is available in an 88-lead LFCSP.

PRODUCT HIGHLIGHTS

  1. Greater than 1 GHz, ultrawide complex signal bandwidth
    enables emerging wideband and multiband wireless applications.
  2. Advanced low spurious and distortion design techniques provide high
    quality synthesis of wideband signals from baseband to high
    intermediate frequencies.
  3. JESD204B Subclass 1 support simplifies multichip
    synchronization in software and hardware design.
  4. Fewer pins for data interface width with serializer/ deserializer
    (SERDES) JESD204B eight-lane interface.
  5. Programmable transmit enable function allows easy design balance
    between power consumption and wake-up time.
  6. Small package size with 12 mm × 12 mm footprint.

Suggested Companion Products


Recommended Analog Quadrature Modulators for the AD9144
  • For a seamless DAC output interface with intergrated Fractional-N PLL and VCO, we recommend the ADRF672x or the ADRF670x family like the ADRF6720 or the ADRF6701.
  • For fixed gain and two differential baseband inputs in low IF-to RF applications, we recommend the ADL537x family like the ADL5372 or the ADL5375.
Recommended Clock Drivers for the AD9144
  • For multioutput clock generators with integrated VCO's, we recommend the AD9516-x family like the AD9516-0.
  • For one input, two outputs, ultrafast clock/data buffer, we recommend the ADCLK925.
Recommended Power Solutions
  • For selecting voltage regulator products, use ADIsimPower.
