Highly-integrated quad 16-bit DAC delivers 2.4GSPS bandwidth

08-05-2015 | Digikey | Semiconductors

Digi-Key now stocks the Analog Devices AD9154-EBZ, AD9154-M6720-EBZ and AD9154-FMC-EBZ which support the AD9154 - a quad, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a maximum sample rate of 2.4 GSPS, permitting multicarrier generation up to the Nyquist frequency in baseband mode. The AD9154 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 the ADRF672x radio frequency quadrature modulators (AQMs) from Analog Devices, Inc. In Mix-Mode, the AD9154 DACs can reconstruct carriers in the 2nd and 3rd Nyquist zones. A serial port interface (SPI) provides for programming / readback of internal parameters. Full-scale output current can be programmed over a range of 4mA to 20mA, says the company.
