ADCs offer high performance, power efficiency

Oct. 27, 2009
Analog Devices Inc. has expanded its low-power data converter portfolio with 26 ADCs (analog-to-digital converters) for effective high-performance, power-efficient communications, portable device, instrumentation, and healthcare applications.

Normal0014612628215322711.1282000Analog Devices Inc. has expanded its low-power data converter portfolio with 26 ADCs (analog-to-digital converters) for effective high-performance, power-efficient communications, portable device, instrumentation, and healthcare applications. The offering reportedly includes three data converter technology industry firsts for 16-bit ADCs: AD9269 is a 16-bit 80MSPS low-power, dual ADC with quadrature-error correction (QEC); AD9265 is a single-channel, 16-bit low-power ADC spanning 80 to 125 MSPS (megasamples per second); and the AD9266 is a small, single-channel 16-bit low-power ADC spanning 20 to 80 MSPS.

These new ADC products offer designers a flexible platform to differentiate their systems without changing the core design by migrating either resolution or bandwidth support by means of space-efficient, pin-compatible families. In addition, the new ADCs’ energy efficiencies provide significant power consumption improvement without impacting system-level performance. In addition to these converters and their various speed grades, the company also introduces 23 single-channel low-power ADCs. The power consumption savings across these ADCs is reportedly as high as 87% compared to equivalent competitive offerings operating comparable ADC functions.

The dual-channel AD9269 16-bit low-power ADC consumes 93 mW per channel, which is 6.5 times lower than competing devices, according to company sources. The product is a monolithic, dual-channel 16-bit, 20/40/65/80 MSPS ADC, featuring a high performance sample-and-hold circuit and on-chip voltage reference. The ADC operates from a 1.8-V supply and contains several features designed to maximize flexibility and minimize system cost, such as programmable clock and data alignment and programmable digital-test-pattern generation. Samples are available now with production quantities available in January 2010.

The single-channel AD9265 low-power, 16-bit ADC was designed to support communications applications requiring low bill-of-material costs, small size, and flexibility. Consuming only 370 mW, it represents a 51% savings compared to competitive low-power solutions. The ADC core features a multistage, differential pipelined architecture with integrated output error correction logic.

The single-channel AD9266 16-bit, low-power ADC is available in a small 5 x 5 mm package, and the pin-out supports resolutions from 10 to 16 bits. The low-power, multistage ADC core is based on a high-performance, sample-and-hold circuit and on-chip voltage reference. The product uses a differential-pipeline architecture with output-error-correction logic to provide 16-bit accuracy at 80 MSPS data rates and guarantees no missing codes over the full operating temperature range. Samples are available now with production quantities available in January 2010.
