Mixed Signal/Analog

Linear Technology has introduced the LTC2753-16, a dual 16-bit current output DAC capable of outputting six unique software-programmable SoftSpan unipolar and bipolar output ranges up to ±10V. Software programmability eliminates the need for expensive precision resistors, gain stages and switching jumpers by hand. The LTC2753-16 offers accurate DC specifications, including ±1LSB (max) INL and DNL over the -40°C to +85°C industrial temperature...

As radio broadcasters in Australia prepare for the imminent launch of digital radio services using the enhanced DAB+ standard, Frontier Silicon has unveiled its latest receiver: Venice 5.1, a DAB+ version of the world’s most widely used digital radio module.

Microchip announces six new 28- and 44-pin 16-bit dsPIC Digital Signal Controllers (DSCs) with a dual-channel, 100ksps, 16-bit audio Digital-to-Analog Conversion (DAC) module for price- or size-conscious embedded system designers who require improved audio performance or wish to add audio playback to existing embedded applications.

Extending its high-performance analog expertise in the medical imaging market, Texas Instruments has introduced a family of fully integrated analog front ends (AFEs) for portable to high-end ultrasound diagnostic equipment. TI‘s AFE58xx family will allow the design of innovative ultrasound systems with superior image quality and reduced power consumption. The first device, the AFE5805, addresses the specific needs of the portable ultrasound...

Linear Technology has introduced the LTC2453, a 16-bit I2C-compatible delta sigma analog-to-digital converter (ADC) in an ultra-tiny 3mm x 2mm DFN package. Its tiny size, low power and guaranteed 16-bit resolution improves performance of portable instruments and sensors. Operating from a single 2.7V to 5.5V supply, the LTC2453 is capable of measuring a differential input up to ±VCC. This wide input range is ideal for measuring a wide variety of ...

Peregrine Semiconductor Corporation has announced the UltraCMOS PE42641 SP4T antenna tuning switch delivering an IMD performance of -110 dBm, making it ideal for converged designs requiring high linearity and low distortion. A variety of emerging market applications benefit from the exceptional RF performance advantages of the PE42641 switch, including 3G GSM/EDGE/WCDMA and CDMA handset and PC card applications; machine-to-machine applications su...

Farnell has further increased the range of National Semiconductor products it stocks with the addition of two new exciting product ranges from the company’s energy-efficient PowerWise family. The ten new buck switching regulators plus three high-speed differential amplifiers mean that Farnell now stocks over 2,000 National Semiconductor parts from the company’s high-performance analogue portfolio. Farnell has an ongoing commitment to add the ...

Analog Devices has introduced a digitally programmable variable gain amplifier (VGA) with transmit driver that sets a new standard of performance for driving signals over power lines, cables, and other applications with low impedance. The AD8260 operates on a single 3.3-V power supply and has a transmit driver that produces ±200-mA output up to 100 kHz, and greater than ±100-mA above that frequency. This is an improvement over competing solutio...

Dialog Semiconductor has announced its new SmartXtend technology that will allow the main displays of many mobile devices – particularly those offering W-QVGA and QVGA resolution – to utilize passive matrix OLED displays rather than LCD or active matrix OLEDs. Passive matrix OLEDs are available at a much lower cost compared to active matrix OLEDs while providing the same advantages in terms of video quality and performance.

Texas Instruments has introduced a family of quad-channel digital-to-analog converters (DAC) with ultra-low glitch (0.15nV-s) and an internal 2.5V reference with 2ppm/C temperature drift and 0.02 percent initial accuracy. This multi-purpose family of 16-, 14- and 12-bit devices offers breakthrough multi-channel performance with the combination of high accuracy, low power consumption and small footprint, making them attractive options for portable...
