Product Summary

The AD9225ARS is a monolithic, single supply, 12-bit, 25 MSPS, analog-to-digital converter with an on-chip, high performance sample-and-hold amplifier and voltage reference. The AD9225ARS uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 25 MSPS data rates, and guarantees no missing codes over the full operating temperature range. The AD9225ARS combines a low cost high speed CMOS process and a novel architecture to achieve the resolution and speed of existing bipolar implementations at a fraction of the power consumption and cost.
