Mixed Signal/Analog

Linear Technology introduces the LTC2378-20, a 20-bit 1Msps no latency successive approximation register analog-to-digital converter with exceptionally low 0.5ppm (typ) and 2ppm (max) Integral Non-Linearity error. INL is a key specification in precision applications, such as seismic monitoring and semiconductor fabrication, indicating how much the ADC transfer function deviates from its ideal.

Maxim is now shipping the MAX11156, the industry’s smallest 12-pin, 18-bit successive approximation register analog-to-digital converter. Available in a tiny 3mm x 3mm TDFN package, the MAX11156 integrates an internal reference and reference buffer, saving cost and at least 70% board space over competing solutions. With 18-bit resolution, this high-performance ADC features Beyond-the-Rails technology, which supports a ±5V input from a single p...

In this interesting article from ES Design magazine, Horst Gether, Product Manager, ams AG, poses the following question: Can active noise cancelling improve speech intelligibility even in a single-ear headset? Read on to find out.

Nowadays many microcontrollers have an internal D/A converter with a resolution of 8-12 bits. This is enough to meet most application requirements but sometimes a higher resolution is needed. A lower resolution may also be good enough if the D/A converter has ideal characteristics, but often non-linearity means the D/A converter can’t be used.

Wolfson Microelectronics has today announced that its WM5102 High Definition Audio System-on-a-Chip, and its WM2000 earpiece driver with Wolfson’s class-leading ambient noise cancellation technology built-in, has been selected by Lenovo for its latest flagship smartphone, the IdeaPhone K900.

Maxim Integrated Products announced it is sampling the MAX14920/MAX14921, high-accuracy, 12/16-channel cell-measurement analog front-ends that lower battery-management electronics costs by up to 35%.

Texas Instruments have announced the introduction of the industry’s first 8-channel pulse-width modulator audio processor with dual asynchronous sample rate converters integrated on a single chip. The HD-compatible TAS5548 allows home and pro audio designers to seamlessly mix two audio sources, providing design flexibility and cost savings compared to competitive solutions that require two chips.

Wolfson Microelectronics and Sensory have announced the availability of Sensory's TrulyHandsfree Voice Control and audio detect front-end on Wolfson’s latest ultra-low power platforms for mobile phone audio channel processing. This combination of leading-edge embedded software and DSP technologies enables unprecedented performance for voice activation and hands-free operation of mobile devices.

Pericom Semiconductor today announced the expansion of its USB 3.0 5Gb ReDriver Signal Conditioning product family. The new additions offer the industry’s smallest footprint at 2mmx2mm, and lowest power in both operating and all important slumber mode (3.63mW), making them ideal for battery powered mobile devices, such as tablets, smart phones, and notebooks.

Mindspeed Technologies today announced its M31285, new low-power, multi-rate, serial digital interface reclocker with integrated fully featured dual cable drivers in a compact 4x4 mm² package providing up to 50 percent power savings compared to competitive solutions.
