AD9148BBCZRL

The AD9148 is a 4-channel, 16-bit, high dynamic rangeDigital-to-analog converters(DAC) that provides a sample rate of 1000 MSPS. It has features optimized for direct conversion transmission applications, including gain, phase, and offset compensation. The DAC output is optimized to interface seamlessly with analog quadrature modulators, for exampleADL5371/ADL5372/ ADL5373/ADL5374/ADL5375/Wait. The serial peripheral interface (SPI) allows programming of the device's internal parameters. The full-scale output current can be programmed from 10 mA to 30 mA. The device operates from 1.8 V and 3.3 V supplies and consumes 3 W total when operating at the maximum sample rate. It is available in a 196-pin chip-scale ball grid array package with an optional heat sink.
Product Focus

• 1. Using low noise and intermodulation distortion (IMD) characteristics, high-quality synthesis can be achieved in wideband signals from baseband to high IF
• 2. Proprietary DAC output switching technology enhances dynamic performance.
• 3. The current output is easy to configure and can be used in various single-ended or differential circuit topologies.
• 4. The data input interface includes FIFO to simplify input timing.
