ADCs deliver ultra-low-power consumption, high performance

Woburn, Mass. — Kenet Inc. has expanded its family of analog-to-digital- converter (ADC) products with the release of its pin-compatible family of 12- and 14-bit ADCs. The new products, fabricated with Kenet's proprietary FemtoCharge CMOS technology, combine ultra-high performance with extremely low-power consumption.

For example, the 12-bit KAD5512-50 operates at sampling rates of 500 million samples per second (MSPS) while consuming less than 370 mW of power, which is nearly an order of magnitude less than available products, said Kenet. In addition, the KAD5512-50 delivers a SNR of 66.3 dB and SFDR of 70 dB at Nyquist frequencies.

At 250 MSPS, the KAD5514-25 ADC is said to offer the industry's highest speed/power ratio in a 14-bit ADC, consuming less than 320 mW. With this product, users can now obtain unprecedented sampling rates and competitive SNR and SFDR specifications while reducing power consumption by up to four times, said the company.

The new family also includes single and dual 12-bit, 250-MSPS products with lower speed grades at 210, 170 and 125 MSPS available for each. For example, the 12-bit KAD5512-25 runs at sampling rates up to 250 MSPS, offering competitive SNR and SFDR specifications while cutting power consumption to less than 190 mW, less than half of competitive products, according to Kenet. Pin-compatible 10-bit versions are also offered.

The 12-bit 250-MSPS dual-channel KAD5612-25 is also said to offer unparalleled SNR and SFDR specifications while cutting power consumption to less than 370 mW for both ADC channels. Pin-compatible 10-bit versions are also available in the dual configuration.

The ADC family incorporates features such as SPI port programmability, making them easy to use and adaptable to a variety of applications. All of the ADCs are available in pin-compatible, 72-pin QFN packages and offer output choices of LVCMOS, SDR LVDS and DDR LVDS, in both single and dual configurations. In addition, the single 12- and 14-bit 250-MSPS ADCs can be ordered in a 48-pin package. All packages are specified over the full industrial temperature range of -40° to +85°C.

Pricing: The KAD5512-50, KAD5512-25, KAD5612-25 and KAD5514-25 products are priced at $125.00, $59.00, $89.00, $89.00 per unit, respectively, all in quantities of 1,000.
Availability: Evaluation boards are currently available for all the 12-bit and 14-bit products, with full production scheduled for first quarter 2008.
