Analog Devices Inc. AD9154 Quad, TxDAC+® DAC

Analog Devices AD9154 Quad, 16-bit TxDAC+® Digital-to-Analog Converter (DAC) offers a high dynamic range with a maximum sample rate of 2.4GSPS to enable multicarrier generation up to the Nyquist frequency in baseband mode. Designed to meet the JESD204B standard, the AD9154 DAC includes features optimized for direct conversion transmit applications such as complex digital modulation, input signal power detection, and gain, phase, and offset compensation. A 4-wire serial port interface allows for programming/readback of internal parameters. The full-scale output current can be programmed over a range of 4mA to 20mA. Available in an 88-lead LFCSP package, the AD9154 DAC is ideal for wireless & wideband communications, transmit diversity, multiple-input/multiple-output (MIMO), instrumentation, and automated test equipment.
