High-resolution ADCs -- an overview Designers engaged in industrial and data-acquisition projects are likely to confront some of these analog-to-digital conversion issues: 1)Digitizing an input signal that extends over a very wide dynamic range, such as delivered by an environmental sound pressure meter able to detect signals over a 60 to 80-dB signal range; 2)Accommodating signals from different sources that exhibit quite different signal ranges; 3)Resolving small changes around a certain value, so that the objective would be to expand the range around that point. 16-bit 80-MSPS ADC offers lowest power, reduced noise The 16-bit no-missing-codes 80-Msample/s A/D converter (ADC) dissipates 89 mW, which is claimed to be less than half the power of competing 16-bit solutions. 16-bit SAR ADC achieves 94-dB SNR The 16-bit LTC2393-16 SAR A/D converter achieves 94-dB SNR at sample rates up to 1 Msamples/s with no cycle latency. ADC driver settles to 16 bits in 350 ns Suitable for driving the latest highest-performance SAR ADCs, the LTC6350 rail-to-rail input and output ADC driver settles to 16 bits in just 350 ns. 16-bit ADCs integrate precision reference The 16-bit LTC2470 and LTC2472 delta sigma A/D converters integrate a 1.25-V reference that offers 2-ppm/ C drift performance and 0.1 percent initial accuracy for precise measurement in space-constrained applications. ADC provides true 16-bit performance Suited for industrial power-grid monitoring and protection applications, the MAX11046 simultaneous-sampling SAR ADC provides "true" 16-bit (no missing code) performance that exceeds the industry standards of the IEC 62053 Class 0.2 and EN 50160. Stereo ADC offers low pin-count Housed in a SOIC-8 package, the WM8783 stereo A/D converter is designed to offer high-quality line input audio performance in recordable-media applications, including LCD TVs, set-top boxes, and DVD recorders. Sigma-delta ADCs achieve low noise Suited for portable instrumentation, industrial process controls, medical monitoring devices, and other applications that require reliable, highly accurate signal conversion, the AD7170 and AD7171 A/D converters have a 125-Hz output data rate and achieve 12- and 16-bit noise-free resolution, respectively. Dual-ch low-power ADC spans 20 to 80 MSPS The dual-channel 16-bit, 20/40/65/80 Msamples/s AD9269 A/D converter consumes 93 mW per channel, said to be 6.5 times lower than competing devices. Low-power 16-bit ADC clocks at 125 MSPS Suitable for communication applications, the single-channel 16-bit AD9265 A/D converter consumes 370 mW. The ADC core features a multistage differential pipelined architecture with integrated output error correction logic. The right MCU architecture for your embedded design So many different microcontroller architectures are on the market today that an embedded engineer faces a daunting task when trying to find the right one to satisfy the needs of a design. Product Roundup: Audio/video multimedia ICs Most electronic products today have some form of audio or video capability.
