GENERAL DESCRIPTION
The AD9230-11 is an 11-bit monolithic sampling analog-to-digital converter (ADC) optimized for high performance, low power, and ease of use. The product operates at up to a 200 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) amplifier and voltage reference, are included on the chip to provide a complete signal conversion solution.
