双16位1230 MSPS,TxDAC系列+数字模拟转换器ad9146数据表

　　The AD9146 is a dual， 16-bit， high dynamic range digital-toanalog converter （DAC） that provides a sample rate of 1000 MSPS with nominal supplies and 1230 MSPS with increased supplies， permitting multicarrier generation up to the Nyquist frequency. The AD9146 TxDAC+® includes features optimized for direct conversion transmit applications， including complex digital modulation， and gain and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators， such as the ADL537x F-MOD series from Analog Devices， Inc. A 3-wire serial port interface provides for programming/readback of many internal parameters. Full-scale output current can be programmed over a range of 8.7 mA to 31.7 mA. The AD9146 comes in a 48-lead LFCSP.
