PRODUCT DESCRIPTION

A single clock input is used to control all internal conversion

cycles. The digital output data is presented in straight binary

output format. An out-of-range signal indicates an overflow

condition which can be used with the most significant bit to

determine low or high overflow.

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 operat-

ing temperature range.

PRODUCT HIGHLIGHTS

The AD9224 is fabricated on a very cost effective CMOS

process. High speed precision analog circuits are now combined

with high density logic circuits.

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 AD9224 offers a complete single-chip sampling 12-bit,

40 MSPS analog-to-digital conversion function in 28-lead

SSOP package.

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 per-

formance is excellent.

Low Power—The AD9224 at 415 mW consumes a fraction of

the power of presently available in existing monolithic solutions.

On-Board Sample-and-Hold (SHA)—The versatile SHA

input can be configured for either single-ended or differential

inputs.

The sample-and-hold (SHA) amplifier is well suited for both

multiplexed systems that switch full-scale voltage levels in suc-

cessive channels and sampling single-channel inputs at frequen-

cies up to and well beyond the Nyquist rate.

Out of Range (OTR)—The OTR output bit indicates when

the input signal is beyond the AD9224’s input range.

Single Supply—The AD9224 uses a single +5 V power supply

simplifying system power supply design. It also features a sepa-

rate digital driver supply line to accommodate 3 V and 5 V logic

families.

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.

Pin Compatibility—The AD9224 is pin compatible with the

AD9220, AD9221, AD9223 and AD9225 ADCs.
