The AD9139 is an 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a maximum update rate of 1600 MSPS, permitting multicarrier generation up to the Nyquist frequency. The AD9139 TxDAC+® includes features optimized for wide band communications applications, including 1× and 2× interpolation, a DLL based high speed interface, sample error detection, and parity detection. 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 up to 33 mA. The AD9139 is available in a 72-lead LFCSP.
**Product Highlights**
1. 575 MHz achievable input signal bandwidth.
2. Advanced low spurious and distortion design techniques
provide high quality synthesis of wideband signals from
baseband to high intermediate frequencies.
3. Very small inherent latency variation simplifies both software
and hardware design in the system. It allows easy multichip
synchronization for most applications.
4. Low power architecture improves power efficiency.
**APPLICATIONS**
Wireless communications: 3G/4G and MC-GSM base stations,
