PRODUCT DESCRIPTION

The AD1672 is a monolithic, single supply 12-bit, 3 MSPS analog-to-digital converter with an on-chip, high performance sample-and-hold amplifier (SHA) and voltage reference. The AD1672 uses a multistage pipelined architecture with output error correction logic to provide 12-bit accuracy at 3 MSPS data rates and guarantees no missing codes over the full operating temperature range. The AD1672 combines a high performance BiCMOS process and a novel architecture to achieve its high performance levels.
