PRODUCT DESCRIPTION

The AD9224 is a monolithic, single supply, 12-bit, 40 MSPS, analog-to-digital converter with an on-chip, high performance sample-and-hold amplifier and voltage reference. The AD9224 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 40 MSPS data rates, and guarantees no missing codes over the full operating temperature range.

The AD9224 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.

The input of the AD9224 allows for easy interfacing to both imaging and communications systems. With a truly differential input structure, the user can select a variety of input ranges and offsets, including single-ended applications. The dynamic performance is excellent.

The sample-and-hold (SHA) amplifier is well suited for both multiplexed systems that switch full-scale voltage levels in successive channels and sampling single-channel inputs at frequencies up to and well beyond the Nyquist rate.

The AD9224’s wideband input, combined with the power and cost savings over previously available monolithics, is suitable for applications in communications, imaging and medical ultrasound.

The AD9224 has an onboard programmable reference. An external reference can also be chosen to suit the dc accuracy and temperature drift requirements of the application.
