STMicroelectronics has announced a high performance 24-bit audio DAC that is intended for the mobile music market and provides 103dB signal-to-noise ratio through the whole audio path, while also embedding the company’s innovative PTETM Playback Time Extender processing scheme to minimize power consumption. The single-chip STw5210 audio solution also integrates power management circuitry to simplify system design and enable direct connection to...

Linear Technology has introduced the LTC2751 family of extremely low-power, software-programmable 16-/14-/12-bit digital-to-analog converters (DACs). These current output DACs typically draw only 0.7uA of supply current (2uA max), while generating an output swing up to ±10V. Six unique output voltage ranges can be programmed via SoftSpan™ software, including two unipolar ranges (0V to 5V, 0V to 10V) and four bipolar ranges (±10V, ±5V, ±2.5V...

A new family of 10- and 12-bit, eight-channel (octal) ADCs introduced by Texas Instruments features the industry’s lowest power consumption and smallest size. The new data converters enable smaller and more energy-efficient medical imaging, wireless communications, military guidance, automatic test equipment and video equipment. The ADS5281 family offers high resolution and sampling speeds of up to 65 million samples per second (MSPS), low ...

Analog Devices has expanded its Advantiv advanced television portfolio with a new 12-bit resolution 3D comb video decoder with an integrated 150 MSPS digitizer for Full-HD 1080p input formats. The ADV7802 provides system designers with a complete single-chip solution for improving video image and color quality in advanced high-definition televisions (HDTVs), video-processors, audio/video receiver (AVR) systems and DVD recorders. The new 12-bit 3D...

STMicroelectronics has announced a very high-performance 24-bit audio DAC (digital-to-analog converter) that offers 103dB dynamic range across the entire audio path. Aimed at the mobile music market, the new STw5200 is available in small TFBGA and VFQFPN packages, and soon, in a tiny 2.6 x 2.6mm WLCSP. Simplifying the system design, the DAC can also be directly connected to the battery.

Linear Technology has announced the LTC6702, a fast, micropower dual comparator in a 2mm x 2mm DFN package. With operation down to 1.7V and less than 60uA of maximum current consumption, this tiny device is ideal for portable and battery operated equipment. Low voltage operation is supported by the LTC6702’s input common mode range, which extends 100mV below ground. Despite its low power consumption, the LTC6702 can switch with a toggle rate of...
