High-speed convertor features CMOS benefits
The latest 14bit, 62Msample/s CMOS analogue-to-digital convertor from Texas Instruments is destined for applications in wireless communications, imaging and instrumentation
The device's CMOS process design allows TI to offer a high-performance 14bit data convertor with higher sampling, lower power consumption and lower prices than competition in the 60Msample/s performance range. The ADS5422's signal-to-noise ratio (SNR) performance of 72dB, spurious-free dynamic range (SFDR) of 85dB and 1.2W power consumption makes this device suitable for a variety of existing and emerging high-end systems.

Webcast to address wireless power optimisation
Texas Instruments and Avnet Electronics Marketing will present a live Analog eLab webcast on 'Optimising power in low-power wireless systems' on 12th April 2006
Specific applications include basestation receivers, digital radio, professional studio cameras, magnetic resonance imaging (MRI), spectrum analysers and optical performance monitoring.
'By featuring the highest sampling rate, lower power and an excellent price/performance ratio, the 14bit CMOS ADS5422 marks an exciting expansion of TI's high-speed data convertor portfolio', said Ed Fullman, product marketing manager for TI's high-speed convertor products.
'Customers looking for a complete high-speed solution can combine the ADS5422 with TI's OPA687, an ultra-low noise, wideband, voltage-feedback op amp that delivers the best low-distortion performance required by high-speed ADCs'.
The ADS5422 operates from a single +5V analogue supply and features a high-bandwidth linear track-and-hold, an internal/external reference option, flexible input range and a low DNL of +/-0.5LSB.
The clock input can accept a low-level differential sinewave or square wave signal down to 0.5V peak-peak, further improving the SNR performance.
It also accepts a single-ended clock signal and has flexible threshold levels.
The ADS5422 is available now in a small LQFP-64 package.
Suggested resale pricing starts at $29.00 in 1000-piece quantities.
