PRODUCT DESCRIPTION

PRODUCT HIGHLIGHTS

The AD9243 is a 3 MSPS, single supply, 14-bit analog-to-

digital converter (ADC). It combines a low cost, high speed

CMOS process and a novel architecture to achieve the resolution

and speed of existing hybrid implementations at a fraction of the

power consumption and cost. It is a complete, monolithic ADC

with an on-chip, high performance, low noise sample-and-hold

amplifier and programmable voltage reference. An external refer-

ence can also be chosen to suit the dc accuracy and temperature

drift requirements of the application. The device uses a multistage

differential pipelined architecture with digital output error correc-

tion logic to guarantee no missing codes over the full operating

temperature range.

The AD9243 offers a complete single-chip sampling 14-bit,

analog-to-digital conversion function in a 44-lead Metric Quad

Flatpack.

Low Power and Single Supply

The AD9243 consumes only 110 mW on a single +5 V power

supply.

Excellent DC Performance Over Temperature

The AD9243 provides no missing codes, and excellent tempera-

ture drift performance over the full operating temperature range.

Excellent AC Performance and Low Noise

The AD9243 provides nearly 13 ENOB performance and has an

input referred noise of 0.36 LSB rms.

The input of the AD9243 is highly flexible, allowing for easy

interfacing to imaging, communications, medical, and data-

acquisition systems. A truly differential input structure allows

for both single-ended and differential input interfaces of varying

input spans. The sample-and-hold amplifier (SHA) is equally

suited for both multiplexed systems that switch full-scale voltage

levels in successive channels as well as sampling single-channel

inputs at frequencies up to and beyond the Nyquist rate. Also,

the AD9243 performs well in communication systems employ-

ing Direct-IF Down Conversion since the SHA in the differen-

tial input mode can achieve excellent dynamic performance well

beyond its specified Nyquist frequency of 1.5 MHz.

Flexible Analog Input Range

The versatile onboard sample-and-hold (SHA) can be configured

for either single ended or differential inputs of varying input spans.

Flexible Digital Outputs

The digital outputs can be configured to interface with +3 V and

+5 V CMOS logic families.

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 (OTR) signal indicates an

overflow condition which can be used with the most significant

bit to determine low or high overflow.
