Mixed Signal/Analog

Analog Devices has introduced a zero-drift, digitally-programmable instrumentation amplifier (in-amp). Rated over an extended industrial temperature range, the AD8231 is suited for a variety of sensors, including resistance temperature detectors, thermocouples and automotive pressure sensors, in harsh environments where minute signal variations must be accurately detected in the presence of large common-mode voltages.

Silicon Laboratories has announced the extension of its broadcast audio product portfolio to include the Si473x AM/FM receiver family. The Si473x enables an AM/FM receiver to be easily added to consumer devices such as clock and portable radios, home stereos, MP3 players, docking stations and mobile handsets.

Texas Instruments has introduced two 14- and 12-bit, 210-MSPS analog-to-digital converters (ADCs) to its pin-compatible, high-speed ADS5546 family. The ADS5547 and ADS5527 provide the highest performance at 210 MSPS with up to 73.3-dBFS signal-to-noise ratio (SNR) and 85-dBc spurious-free dynamic range (SFDR) at 70 MHz input frequency .

Comprising the ZXCZM800 multi-channel digital modulator and the ZXCZA200 analog feedback processor, a digital amplifier chipset from Zetex Semiconductors has been introduced to create audio products capable of producing a sound quality to rival that of the best linear amplifiers. Based on Zetex Semiconductors’ unique Class Z direct digital feedback amplifier (DDFA) architecture, the chipset enables high performance products suc...

Analog Devices, Inc. is continuing to expand its broad line of HDMI™ interface ICs with the availability of HDMI v1.3-compatible multiplexer, receiver and transmitter circuits that are helping the high-definition (HD) video market achieve new levels of picture quality and power efficiency. The industry’s broadest portfolio of HDMI (High-Definition Multimedia Interface™) components now includes devices that address the increasing...

Microchip announces the highest resolution analogue-to-digital converter available in a 6-pin SOT-23 package. The low-power, 18-bit, Delta-Sigma MCP3421 ADC features an integrated voltage reference, oscillator and Programmable Gain Amplifier (PGA), which reduce the need for external components and enables a smaller overall design.

Catalyst Semiconductor has added five new 32-tap devices to its extensive family of over 30 Digitally Programmable Potentiometers [DPP(tm)]. The CAT5123, CAT5124 and CAT5125 are volatile devices, while the CAT5127 and CAT5129 offer non-volatile wiper storage. All of the new Catalyst digital potentiometers feature a user-friendly up/down control interface.

Analog Devices Inc., today introduced the first dual 14-bit analog-to-digital converter (ADC) to achieve sampling rates of 150 mega samples per second (MSPS). Supporting all third-generation (3G) base station wireless standards, including W-CDMA, CDMA2000 and TD-SCDMA, the AD9640 is the only dual 14-bit ADC that samples at rates beyond 135 MSPS, a common requirement for the emerging WiMax (Worldwide Interoperability for Microwave Access) standard...

Today's guitarist wants new equipment that complements the sound of vintage gear but that also offers a wider range of tonal refinements than previously existed. To achieve that Analog Devices, Inc. today announced that Damage Control is leveraging the performance of the SHARC(R) processor to create products that offer the highest quality tone and sonic performance available for some of the world's leading guitarists, such as Robert Randolph, Yn...

Xilinx’s latest high performance field programmable gate array (FPGA) Virtex-5 LX, is now available from DT Electronics. Built on Xilinx’s ExpressFabric architecture, the V5LX allows designs to be packed in 45% less area, operate with up to 30% performance improvement and 35% dynamic power reduction. Each platform within the Virtex-5 family has been optimised to offer a balance of high-performance logic, serial connectivity, signal and embedd...
