AD9146:  Dual, 16-Bit, 1230 MSPS, TxDAC+® Digital-to-Analog Converter

Product Details

Product Status:Recommended for New Designs

The AD9146 is a dual, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a sample rate of 1230 MSPS, permitting multicarrier generation up to the Nyquist frequency.

The AD9146 TxDAC+® includes features optimized for direct conversion transmit applications, including complex digital mod-ulation, and gain and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x F-MOD series from Analog Devices, Inc. A 3-wire serial port interface provides for program-ming/readback of many internal parameters. Full-scale output current can be programmed over a range of 8.7 mA to 31.7 mA. The AD9146 comes in a 48-lead LFCSP.

  • Wireless infrastructure
  • Digital high or low IF synthesis
  • Transmit diversity
  • Wideband communications: LMDS/MMDS, point-to-point


  1. Ultralow noise and intermodulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high intermediate frequencies.
  2. A proprietary DAC output switching technique enhances dynamic performance.
  3. The current outputs are easily configured for various single-ended or differential circuit topologies.
  4. Compact LVDS digital interface offers reduced width data bus.


  • Flexible LVDS interface allows byte or nibble load
  • Single-carrier W-CDMA ACLR = 80 dBc at 122.88 MHz IF
  • Analog output: adjustable 8.7 mA to 31.7 mA,
    RL = 25 Ω to 50 Ω
  • Integrated 2×/4× interpolator/complex modulator allows carrier placement anywhere in the DAC bandwidth
  • Gain, dc offset, and phase adjustment for sideband suppression
  • Multiple chip synchronization interfaces
  • High performance, low noise PLL clock multiplier
  • Digital inverse sinc filter
  • Low power: 1.2 W @ 1.0 GSPS, 800 mW @ 500 MSPS, full operating conditions
  • 48-lead, exposed paddle LFCSP
