The AD9142A is a dual， 16-bit， high dynamic range digital-toanalog 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.
