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 to 27.0mA. The AD9144 is available in an 88-lead LFCSP.
- Greater than 1GHz, ultrawide complex signal bandwidth enables emerging wideband and multiband wireless applications
- Advanced low spurious and distortion design techniques provide high quality synthesis of wideband signals from baseband to high intermediate frequencies
- JESD204B subclass1 support simplifies multichip synchronization in software and hardware design
- Fewer pins for data interface width with a serializer/deserializer (SERDES) JESD204B eight-lane interface
