AD9142A:  Dual, 16-Bit, 1600 MSPS, TxDAC+ Digital-to-Analog Converter

Product Details

Product Status:Recommended for New Designs

The AD9142A is a dual, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a sample rate of 1600 MSPS, permitting a multicarrier generation up to the Nyquist frequency. The AD9142A TxDAC+® includes features optimized for direct conversion transmit applications, including complex digital modulation, input signal power detection, and gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x F-MOD series and the ADRF670x series from Analog Devices, Inc. A 3-wire serial port interface provides for the programming/readback of many internal parameters. Full-scale output current can be programmed over a range of 9 mA to 33 mA. The AD9142A is available in a 72-lead LFCSP.


  1. Wide signal bandwidth (BW) 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. Very small inherent latency variation simplifies both software and hardware design in the system. It allows easy multichip synchronization for most applications.
  4. New low power architecture improves power efficiency (mW/MHz/channel) by 30%.
  5. Input signal power and FIFO error detection simplify designs for downstream analog circuitry protection.
  6. Programmable transmit enable function allows easy design balance between power consumption and wakeup time.

Recommended I/Q Modulators for the AD9142A
  • For high performance RF/IF modulation with excellent phase accuracy and amplitude balance, we recommend the ADL5375 or the ADL537x family like the ADL5372.
  • For a family of quadrature modulators with fractional-N PLL's and integrated VCO's, we recommend the ADRF670x family like the ADRF6702.
Recommended Clock Generator with VCO for the AD9142A
  • For a multi-output, low jitter, low phase noise clock generator, we recommend the AD9516-x family like the AD9516-0.
Recommended Power Solutions
  • For selecting voltage regulator products, use ADIsimPower.
