Mixed Signal/Analog

Wolfson Microelectronics announced the launch of the WM8912, an ultra low power DAC designed to significantly extend playback time, reduce system cost and dramatically enhance audio performance in portable applications, including media players, headsets, multimedia phones and navigation devices.

Linear Technology has announced a family of 24 ultralow power 14-bit/12-bit, 125Msps to 25Msps, quad and dual ADCs that dissipate as little as one-third the power of competing ADCs. The flagship ADC is the LTC2175-14, a quad 14-bit, 125Msps ADC that dissipates only 558mW (140mW per channel). The LTC2175 significantly reduces system power without sacrificing AC performance, offering signal to noise ratio (SNR) performance of 73.4dB and spurious fr...

Linear Technology introduced the LTC2757, an 18-bit digital-to-analog converter (DAC) to offer precision DC specifications of ±1LSB INL (max) and ±1LSB DNL (max). The LTC2757 is 18-bit accurate over a ±10V output range, offering a full-scale settling time of 2.1µs and low 1.4nV•s glitch impulse. Fast settling and low glitch reduce harmonic distortion, making it possible to produce higher frequency, lower noise output waveforms. This unique...

Maxim introduced the MAX11046, an 8-channel, 16-bit simultaneous-sampling ADC. An unique architecture (patent pending) provides an ultra-low-noise, on-chip, negative supply voltage. This innovation achieves true 16-bit performance from a high-impedance bipolar input using only a single positive external supply, and exceeds the regulatory requirements for Class 0.2 (0.2% of 220V) precision mandated by IEC 62053.

Linear Technology has introduced the LTC2463, a 16-bit delta sigma ADC that integrates a precision reference in tiny 12-lead 3mm x 3mm DFN and 4mm x 5mm MSOP packages. With the device's integrated reference (2ppm/°C typical, 10ppm/°C maximum), the LTC2463 allows precise measurements with no need for an external reference. The LTC2463 communicates via a 2-wire I2C interface and is a complete analog solution for portable sensors, compact systems ...

Texas Instruments has introduced the 100-kSPS ADS8201, a complete on-chip data acquisition system (DAS) that draws only 600 uA of supply current at 2.2 V, resulting in up to 75 percent power savings over discrete implementations. The ADS8201 offers customers system-processing capability by integrating a complete analog signal chain of four chips into one.

Peregrine Semiconductor announced the first pair in a series of new SPDT RF switches addressing the needs of wireless infrastructure, 2.4GHz Industrial, Scientific and Medical (ISM), and broadband applications for fiber optics and Multichannel Multipoint Distribution Service (MMDS). The PE4250 and PE4251are the result of a joint design and development activity with long-standing partner OKI Electric Ltd. (Tokyo). Product engineers from both OKI a...

Linear Technology has introduced the LT2940, a power and current monitor for 4V to 80V systems. The LT2940 provides the necessary circuits to accurately measure, monitor and control power in situations where both the current and voltage may vary due to supply voltage uncertainty, component parametric changes, transient conditions or time-varying signals.

Linear Technology has announced the LTC2635 quad 12-bit, 10-bit and 8-bit rail-to-rail digital-to-analog converters (DACs), which integrate a precision 10ppm/ºC reference in tiny 3mm x 3mm QFN and MSOP packages. Ordering options include 2.5V (LTC2635-L) and 4.096V (LTC2635-H) DAC full-scale outputs. In addition to offering power-on reset to zero and mid-scale options, the LTC2635-L also includes ordering options for high impedance outputs at po...

Intersil, a world leader in the design and manufacture of high-performance analogue and mixed-signal semiconductors, will showcase its latest products and technologies at the Consumer Electronics Show.
