The AD9128 is a dual, 16-bit, high dynamic range, digital-to-analog converter (DAC) that supports 1.25GSPS signal processing with JESD204A serial interface. It is low power and has adjustable output current of 8.7mA to 31.7mA. It is suitable for wireless infrastructure, transmit diversity, wideband communications and other applications.
The AD9128 is a dual, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a sample rate of 1.25 GSPS. It is optimized for direct conversion transmit applications, supporting complex digital modulation and multi-carrier generation up to the Nyquist frequency. The device features four high-speed JESD204A compliant data lanes to reduce interface connections and includes a multi-chip synchronization interface for deterministic latency alignment.
