Stay up-to-date on the latest new products from Analog Devices!

Introducing our quarterly blog post series, Product Round-up. This blog will provide a summary of products featured in press releases from the previous quarter, so you can stay well-informed on the latest technology from some of the best designers in the world. In this quarterly series, you can discover the parts that you need for your project, learn more about ADI's extensive list of product offerings, and find resources to stay connected in EngineerZone. Read on to get the details on the newly launched products, view the schematics, and find related content in EngineerZone.

SHARC® Audio Module (SAM)

In September, Analog Devices, Inc. announced a full audio system that features the SHARC® Audio Module (SAM) for the creation of digital audio devices, including audio FX processors, multi-channel audio systems, MIDI synthesizers, and other DSP-based audio systems.

SAM includes the dual-SHARC+ core ADSP-SC589 audio processor SoC (with an integrated Arm® Cortex®-A5 core) and leverages Analog Devices’ A2B audio bus technology. In addition to the main SHARC audio module board, ADI offers daughter boards to provide added functionality to the main board and expand the audio system. The Audio Project Fin board mates directly to the main board, providing MIDI input/output as well as pushbuttons and potentiometers to modify audio effects. The A2B Amplifier Module features two high-efficiency Class-D amplifiers to output digital audio data received over the twisted-wire pair A2B bus from PDM microphones and/or serial TDM sources on the main board (or another connected A2B node).

In October, Analog Devices introduced the AD7134 alias-free analog-to-digital converter (ADC) that significantly simplifies front-end design and speeds up time to market for precision DC-350kHz applications.

We've heard your feedback. Traditional precision data-acquisition signal chain design is a time-consuming activity as designers balance anti-alias filter requirements, passive component tolerances, phase and gain errors, as well as high-speed ADC drive requirements. The AD7134 introduces a new architecture for precision ADCs that fundamentally changes the design process. The new device removes the need for anti-alias filter, and its resistive input significantly simplifies ADC drive.

In November, Analog Devices introduced a reference design and algorithm that enables small form factor, low power, smoke detector designs to be rapidly prototyped and brought to market faster at a reduced cost. The new CN0537 reduces design risk and has been tested and verified to pass the UL 217 Standard for Smoke Alarms, 8th edition. In October, ADI experts presented a webcast on How to Design Better Smoke Detectors To Meet New Regulatory Requirements. The reference design uses Analog Devices’ ADPD188BI high performance optical sensor core combined with precision smoke chamber for reduced nuisance alarms.

In December, Analog Devices introduced the LT8491 buck-boost battery charging controller that features Maximum Power Point Tracking (MPPT), temperature compensation and I2C interface for telemetry and control. The device operates from input voltages above, below or equal to the regulated battery float voltage. The LT8491 offers three selectable Constant Current Constant Voltage (CC-CV) charging profiles, making it ideal for charging a variety of battery chemistry types including sealed lead acid, gel and flooded cells, and Li-Ion. All charge termination algorithms are provided onboard, eliminating the need for software or firmware and thus reducing design cycle time.
