High-speed ADCs offer best SNR, low power

The 12-bit ISLA212Pxx and 14-bit ISLA214Pxx A/D converters offer maximum sampling rates of 130, 200, and 250 Msamples/s and are claimed to offer the industry’s best signal-to-noise ratios for high speed 12- and 14-bit ADCs (over 73.0 dBFS at 14-bits and 70.5 dBFS at 12-bits for input frequencies up to 105 MHz) while consuming less than 450 mW from a single 1.8-V supply. Based on the company’s FemtoCharge technology, they also offer a low clock jitter of 75 fs, support for multiple ADC synchronization, optimized output timing, and an SPI port.

The ISLA212Pxx and ISLA214Pxx series are available now in a 10 x 10 mm, 72-pin QFN and will also be available in a 7 x 7, mm 48-pin QFN package. These pin-compatible parts offer channel-to-channel balance and SDR/DDR LVDS-compatible or LVCMOS outputs.(From $24.55 ea/1,000 — available now)
