AD9142A Digital-to-Analog Converter

Dual, 16-bit, 1600 MSPS, TXDAC+ digital-to-analog converter

Image of Analog Devices' AD9142A Digital-to-Analog ConverterAnalog Devices' 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.


  • Supports input data rate up to 575 MHz

  • Proprietary low spurious and distortion design 6-carrier GSM ACLR = 79 dBc at 200 MHz IF SFDR > 85 dBc (bandwidth = 300 MHz) at ZIF
  • Flexible 16-bit LVDS interface supports word and byte load data interface DLL sample error detection and parity
  • Multiple-chip synchronization fixed latency and data generator latency compensation
  • Selectable 2×, 4×, 8× interpolation filter low-power architecture fS/4 power-saving coarse mixer
  • Input signal power detection emergency stop for downstream analog circuitry protection
  • FIFO error detection


  • Wireless communications: 3G/4G and MC-GSM base stations, wideband repeaters, software-defined radios
  • Wideband communications: point-to-point, LMDS/MMDS
  • Transmit diversity/MIMO
  • Instrumentation
  • Automated test equipment
