Hot-selling and scarce AD9788BSVZ Dual 12-/14-/16-Bit 800 MSPS DAC TQFP100 spot stock

 Product Descriptions

The AD9785/AD9787/AD9788 are 12-bit, 14-bit, and 16-bit,high dynamic range TxDAC® devices, respectively, that providea sample rate of 800 MSPS, permitting multicarrier generationup to the Nyquist frequency. Features are included for optimizingdirect conversion transmit applications, including complexdigital modulation, as well as gain, phase, and offset compensation . The DAC outputs are optimized to interface seamlesslywith analog quadrature modulators, such as the ADL537xfamily from Analog Devices, Inc. A serial peripheral interface(SPI) provides for programming and readback of many internalparameters. Full-scale output current can be programmed overa range of 10 mA to 30 mA. The AD978x family is manufacturedon a 0.18 μm CMOS process and operates from 1.8 V and 3.3 Vsupplies . It is enclosed in a 100-lead TQFP package .
