PRODUCT DESCRIPTION

The AD9226 is a monolithic, single-supply, 12-bit, 65 MSPS analog-to-digital converter with an on-chip, high-performance sample-and-hold amplifier and voltage reference. The AD9226 uses a multistage differential pipelined architecture with a patented input stage and output error correction logic to provide 12-bit accuracy at 65 MSPS data rates. There are no missing codes over the full operating temperature range (guaranteed).
