The industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, Mouser Electronics, Inc., is now stocking the AD5767 12-bit voltage output denseDAC digital-to-analog converter (DAC) from Analog Devices Inc. Designed to reduce the system footprint for wired telecommunications systems without compromising performance, the 16-channel DAC provides the required discrete components and necessary bias ranges for coherent, fiber-based optical systems from medium- to long-haul implementations.
The Analog Devices AD5767 DAC, available from Mouser Electronics, delivers a broad range of unipolar or bipolar output voltages from the user-supplied 2.5 V reference. Engineers can monitor each of the DAC’s 16 channels using the integrated output voltage multiplexer, and adjust each output from a minimum output voltage of -20 V to a maximum output voltage of +14 V.
The output buffers on the DAC can also sink or source up to 20 mA, and, if needed, the DAC can execute low-frequency dithering functionality, which eliminates the need for external circuitry. This reduction of external components makes the DAC highly desirable for indium phosphide Mach-Zehnder modulator (InP MZM) biasing applications. For communications, the AD5767 features a versatile four-wire serial interface that operates at a clock rate of up to 50 MHz for write mode and is compatible with a serial peripheral interface (SPI), QSPI, MICROWIRE, and DSP interface standards.
Analog Devices’ AD5767 DAC is now in stock at Mouser Electronics in a space-saving 4 mm × 4 mm WLCSP package and 6 mm × 6 mm LFCSP package. The DAC features a wide operating temperature range of minus 40 degrees to 105 degrees Celsius, and is suited for industrial automation, optical networking, analog output modules, test and measurement equipment, and data acquisition applications.
The AD5767 DAC is supported by the full-EVAL-AD5767 evaluation board, which integrates an Analog Devices ADP5071 switching regulator to offer a complete power solution. The evaluation board enables designers to control the AD5767 DAC using the USB port of a Windows-based PC running Analog Device’s Analysis, Control, Evaluation (ACE) evaluation software. The ACE software provides an intuitive graphical user interface (GUI) to configure modes of operation through the synchronous serial port interface.
