MK120441 (ADI AD9645BRichardson RFPD Inc. announces immediate availability and full design support capabilities for a new dual, 14-bit analog-to-digital converter (ADC) from Analog Devices, Inc. (ADI). The AD9645 includes an on-chip sample-and-hold circuit designed for low cost, low power, small size and ease of use.

The device operates at a conversion rate of up to 125 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical, including diversity radio systems, 3G and 4G Cellular, smart antenna systems, broadband data applications, portable medical imaging and ultrasound, and Radar/LIDAR.

Additional key features of the AD9645 include:

  • 1.8 V supply operation
  • Low power: 122 mW per channel at 125 MSPS with scalable power options
  • SNR = 74 dBFS (to Nyquist)
  • SFDR = 91 dBc at 70 MHz
  • DNL = ±0.65 LSB (typical); INL = ±1.5 LSB (typical)
  • Serial LVDS (ANSI-644, default) and low power, reduced range option (similar to IEEE 1596.3)
  • 650 MHz full power analog bandwidth
  • 2 V p-p input voltage range

Serial port control that includes full chip and individual channel power-down modes, flexible bit orientation, built-in and custom digital test pattern generation, clock divider, programmable output clock and data alignment, programmable output resolution, and standby mode.

The AD9645 is part of ADI's Select Products for Q4, 2012. Common configurations are in stock and available for immediate delivery. The device is also available by calling 1-800-737-6937 (within North America); or please find your local sales engineer (worldwide) at local sales support.
