Analog Devices Inc. AD9139 16-Bit Digital-to-Analog Converters
Analog Devices Inc. AD9139 16-Bit Digital-to-Analog Converters offer a high dynamic range and provides a sample rate of 1600MSPS, permitting a multi-carrier generation up to the Nyquist frequency.
The AD9139 TxDAC+® includes features optimized for wideband communication applications, including 1× and 2× interpolation, a Delay-Locked Loop (DLL) powered high-speed interface, sample error detection, and parity detection. A 3-wire serial port interface provides for the programming/readback of many internal parameters. A full-scale output current can be programmed over a range of 9mA up to 33mA. The AD9139 is ideal for wideband communications, transmit diversity/MIMO, instrumentation, and automated test equipment.
