Description
AI
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.The ADC requires a 1.8 V analog voltage supply and a differential clock for full performance operation. The digital outputs are LVDS (ANSI-644) compatible and support twos complement, offset binary format, or Gray code. A data clock output is available for proper output data timing.Fabricated on an advanced CMOS process, the AD9230-11 is available in a 56-lead lead frame chip scale package, specified over the industrial temperature range (−40°C to +85°C).Product HighlightsHigh Performance.
