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.
The BLIP ADSP-BF707 is a small-form-factor development platform that offers end equipment manufacturers multiple functional profiles covering intelligent motion sensing, people counting, vehicle detection, and face detection use cases. The BLIP ADSP-BF707 platform includes an intuitive configuration GUI and enables real-time analysis of captured video, as well as video output/display through an on-board USB port. This makes it a highly valuable tool for product development and accelerating time to market.
Additional key features include advanced occupancy detection with optimized imaging modules and demos; ADSP-BF707 Blackfin processor with more than 1-Mbyte of internal SRAM and LPDDR support; and on-board CMOS image sensors from Omnivision and Aptina USB powered, complete with ICE-1000 and CrossCore Embedded Studio development tools.
The ADSP-BF706 EZ-KIT Mini development platform offers designers a complete, small-form-factor, low-cost starter platform with on-board, high-quality audio I/O, large internal SRAM and multiple connectivity options including USB. The platform leverages ADI’s optimized development tools and includes DSP Concepts’ graphical-based Audio Weaver software tool to provide a full-featured audio module library with efficient code generation and profiling.
Additional key features include low-cost, ultra-low-power ADSP-BF706 Blackfin processor with an ADAU1761 audio codec; multiple audio project options including use of Audio Weaver as well as development with the Arduino-compatible interface; all USB powered with on-board debug agent and CrossCore Embedded Studio development tools.
New flexible D/A converter
Analog Devices also introduced a single-chip, universal output D/A converter which combines a 16-bit data converter, ±2 ppm/°C 2.5-V 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.
Offering a 60 percent space savings over previous discrete solutions, the AD5761R’s single-chip 3-mm × 3-mm LFCSP standard package is ideal for designs within shrinking form factors, such as actuator control. The total unadjusted error specification — ± 0.15% FSR max — is a true error including all on-chip circuitry and reference. This enables more accurate end systems and eliminates multiple system calibration routines in industrial environments. For a lower cost, less accurate option within the same series, a pin compatible 12-bit version and non-reference options are also available.
Complementary low-noise reference products for the AD5761R include the ADR4525 and other products comprising the ADR45XX family. Complementary low-noise positive LDOs include the ADM7160 for 5-V systems, the ADP7118 for 12-V systems and the ADP7142 for 24-V systems. The ADP7182 is a complementary low-noise negative LDO for 5-V, 12-V and 24-V systems.
