Intersil Corporation (NASDAQ Global Select: ISIL), today expanded its growing family of high speed analog-to-digital converters (ADCs) with a new series of devices that provide industry leading signal-to-noise ratios while consuming little power. The new devices offer excellent high input frequency performance, enabling simplified system architectures that improve manufacturability while reducing cost over traditional baseband architectures. The ISLA212Pxx and ISLA214Pxx are 12-bit and 14-bit ADCs with maximum sampling rates of 130, 200 and 250MSPS. The series offers the industry's best signal-to-noise ratios for high speed 12- and 14-bit ADCs (over 73.0dBFS at 14-bits and 70.5dBFS at 12-bits for input frequencies up to 105MHz) while consuming less than 450mW from a single 1.8V supply. The devices use Intersil's proprietary FemtoCharge(TM) technology, which enables very low power consumption without sacrificing the ADC's dynamic performance. They increase accuracy and save power in high-performance data acquisition and instrumentation systems, communications test equipment, broadband or wideband communications systems, software defined radios and radar array processing equipment. The ISLA212Pxx and the ISLA214Pxx are members of Intersil's newest pin-compatible ADC family. Pin-compatibility allows customers to re-use designs developed with any ADC from the family, substituting another ADC with a different resolution or sample rate without modifying the hardware design. Design re-use simplifies system development, reduces design risk and speeds end product time-to-market. To further enhance a designer's first-pass success, Intersil also provides dedicated product line applications support for all customers, large, medium and small. Features and Specifications

  • Multi-channel designs are simplified by synchronization, channel-to-channel balance and optimized output timing
  • Low clock jitter of 75fs maximizes high input frequency performance
  • A serial peripheral interface (SPI) port allows for flexible configurability
Pricing and Availability The ISLA212Pxx and ISLA214Pxx series are available now in a 10mm x 10mm, 72-pin QFN and will also be available in a 7mm x 7mm 48-pin QFN package. Prices for these converters start at $24.55 each in 1,000-unit quantities. For more information on the ISLA212Pxx series please visit For more information on the ISLA214Pxx series please visit
