Analog Devices introduces dual 14-bit analog-to-digital converter for 3G and WiMAX base stations

Analog Devices introduces dual 14-bit analog-to-digital converter for 3G and WiMAX base stations
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.

High-Performance, Small 12-bit, 500 MSPS ADC from TI

 High-Performance, Small 12-bit, 500 MSPS ADC from TI
Texas Instruments has introduced a monolithic 12-bit, 500 MSPS analog-to-digital converter (ADC) providing unmatched size and performance. The new pipeline ADC offers 64.5 dBFS signal-to-noise ratio (SNR) up to 500 MHz input frequency at 500 MSPS, bringing a new class of performance to customers previously confined to 8- and 10-bits of resolution. In a space-saving 14 mm x 14 mm package, the new ADC meets the resolution and speed requirements of applications such as communications, amplifier linearization, test and measurement instrumentation, software-defined radio and radar and imaging systems.

Data Acquisition Device from Semtech Features High Gain for Portable Sensor Applications

Data Acquisition Device from Semtech Features High Gain for Portable Sensor Applications
Semtech has introduced the SX8722, a complete, high-resolution data acquisition device for micro-electromechanical systems (MEMS) sensors used in portable industrial and consumer sensing applications. The SX8722 interfaces with most Wheatstone bridge chemical, pressure or magnetic sensors to condition and read data. The device features Semtech’s ZoomingADC, a 16-bit analog/digital converter (ADC) with a 10-bit preamplifier to allow the device to “zoom in” on a small portion of the analog signal and apply the full 16-bit ADC to that part of the signal.
