72-lead, exposed paddle LFCSP The AD9125 is a dual, 16-bit, high dynamic range TxDAC+В®
digital-to-analog converter (DAC) that provides a sample rate of
1000 MSPS, permitting a multicarrier generation up to the Nyquist
frequency. It 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 4-wire
serial port interface allows 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 AD9125 comes in a …
