New D/A converter and low-cost Blackfin development platforms

26-02-2015 | Analog Devices | Semiconductors

Analog Devices has introduced a single-chip, universal output D/A converter which combines a 16-bit data converter, ±2ppm/C 2.5V reference, output buffer and gain scaling function on-chip. The innovative feature set of the AD5761R converter removes the need for external components, including gain setting precision resisters and amplifiers. In data acquisition and actuator control applications, this quickens and simplifies system design, enabling both unipolar and bipolar operation, through a software register update. Without affecting system design effort, cost or size, the new, flexible D/A converter facilitates design reuse across multi-functional end-equipment, while also enabling enhanced system functionality through the multiple output voltage ranges. Additionally, ADI announced two dual DC-DC regulators that power the new D/A converter with two independently regulated positive and negative rails for power sensitive applications. This simple two-chip solution enables users to generate bipolar 10-V outputs from only a single, low-voltage positive supply rail, which greatly simplifies system design and removes the need for routing multiple high-voltage rails. Low-cost Blackfin processor-based development platforms The company has also launched two low-cost Blackfin processor-based development platforms aimed at demanding ultra-low-power, real-time applications for image sensing and advanced audio. The Blackfin Low Power Imaging Platform (BLIP) leverages the ADSP-BF707 Blackfin processor as well as Analog Devices’ optimized software libraries for video occupancy sensing. The ADSP-BF706 EZ-KIT Mini development platform targets power-sensitive embedded applications from portable audio to sound processing and effects. Both platforms include a license for ADI’s latest CrossCore Embedded Studio development tools and all hardware for real-time debug and development, says the company.
