AD9467 - 16-Bit, 200 MSPS/250 MSPS Analog-to-Digital Converter
The AD9467 is a 16-bit, monolithic, IF sampling analog-to-digital converter (ADC). It is optimized for high performance over wide bandwidths and ease of use. The product operates at a 250 MSPS conversion rate and is designed for wireless receivers, instrumentation, and test equipment that require a high dynamic range.
The ADC requires 1.8 V and 3.3 V power supplies and a low voltage differential input clock for full performance operation. No external reference or driver components are required for many applications. Data outputs are LVDS compatible (ANSI-644 compatible) and include the means to reduce the overall current needed for short trace distances.
A data clock output (DCO) for capturing data on the output is provided for signaling a new output bit. The internal power-down feature supported via the SPI and typically consumes less than 5 mW when disabled. Optional features allow users to implement various selectable operating conditions, including input range, data format select, and output data test patterns.
The AD9467 is available in a Pb-free, 72-lead, LFCSP specified over the −40°C...+85°C industrial temperature range.
