Mixed Signal/Analog

Wolfson Microelectronics has announced the launch of the first devices in its family of silicon microphones due for release over the next 12 months. The WM7110 and WM7120 are compact, high Signal to Noise ratio (SNR) analogue microphones for use in consumer applications requiring low power consumption and excellent signal quality. Using Wolfson’s proprietary CMOS/MEMS membrane technology the new devices deliver high reliability and performance ...

National Semiconductor has introduced a 2.5 GHz fully differential amplifier and a 10-bit, 2 Giga-sample per second (GSPS) single/1 GSPS dual analog-to-digital converter (ADC) that deliver unequaled dynamic system-level performance and low power for wideband applications. These combined signal path products are well-suited for ground-based radar, data acquisition systems, point-to-point base stations and next-generation set-top boxes.

Analog Devices has introduced eight TxDAC transmit digital-to-analogue converters (DACs), each integrating two DACs on a single device. Adding to ADI’s extensive high-speed DAC portfolio, the new pin-compatible dual TxDAC converters are designed for communications, industrial, instrumentation and other demanding high-performance applications for which low power consumption and space savings yield significant cost, performance and time-to-marke...

National Semiconductor has introduced a digital temperature sensor that monitors automotive system temperature up to 175 degrees C and delivers +/- 1 degree C accuracy between 130 degrees C and 160 degrees C. The device is manufactured on an automotive grade flow meeting AEC-Q100 Grade 0 qualification requirements.

Texas Instruments has introduced six 12- and 14-bit analog-to-digital converters (ADCs) with sampling rates as high as 250 MSPS (mega samples per second) to deliver a premium combination of wide signal bandwidth, high dynamic performance and low power consumption, enabling more efficient power amplifier linearization in digital pre-distortion (DPD) solutions, better range and sensitivity in radar and defense electronics and greater accuracy in hi...

Analog Devices has extended its line of audio processing solutions with a pair of codecs (coder/decoders) for high-performance portable audio electronics that deliver longer battery life without compromising audio quality. The ADAU1361 and ADAU1761 24-bit audio codecs are ideally suited for wireless handsets, portable media players, portable navigation devices, digital still cameras and other mobile audio and telephony applications. The ADAU1361 ...

Analog Devices has introduced a high-speed differential amplifier that delivers the industry’s best combination of high performance, low noise and reduced power consumption for engineers driving high-gain ADCs (analogue-to-digital converters) in power-sensitive communications and instrumentation systems. Drawing less than half the current of other devices in its class, ADI’s ADA4927 differential amplifier achieves greater than 80 dB SFDR (spu...

Texas Instruments has introduced a high-resolution (24-bit), high-speed (625kSPS) delta-sigma analog-to-digital converter (ADC). The ADS1672 features a unique combination of wide bandwidth, outstanding AC and DC performance, and a dual-path digital filter to give greater flexibility to designers of automated test equipment, test and measurement, medical instrumentation, vibration analysis and sonar/military equipment.

Texas Instruments has introduced two integrated analog front ends (AFEs) for handheld ultrasound systems. The newest members of TI’s AFE family for medical ultrasound, the industry-first 16-channel AFE5851 and the 8-channel AFE5801 bring breakthrough power efficiency and smaller footprint to support the new market for handheld ultrasound systems that can fit in a doctor’s pocket.

Intersil has developed what it says is the industry’s optimal CD/MP3 stereo 2:1 multiplexer designed to deliver ultra low distortion audio source or load selector solutions with very high signal muting.
