GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD9244 is a monolithic, single 5 V supply, 14-bit,

40 MSPS/65 MSPS analog-to-digital converter with an on-chip,

high performance sample-and-hold amplifier and voltage reference.

The AD9244 uses a multistage differential pipelined architecture

with output error correction logic to provide 14-bit accuracy at

40 MSPS/65 MSPS data rates and guarantees no missing codes

over the full operating temperature range.

Low Power—The AD9244, at 550 mW, consumes a frac-

tion of the power of presently available ADCs in existing

high speed solutions.

IF Sampling—The AD9244 delivers outstanding perfor-

mance at input frequencies beyond the first Nyquist zone.

Sampling at 65 MSPS with an input frequency of 100 MHz,

the AD9244 delivers 71 dB SNR and 86 dB SFDR.

The AD9244 has an on-board, programmable voltage reference.

An external reference can also be used to suit the dc accuracy

and temperature drift requirements of the application.

Pin Compatibility—The AD9244 offers a seamless

migration from the 12-bit, 65 MSPS AD9226.

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

input can be configured for either single-ended or differ-

ential inputs.

A differential or single-ended clock input is used to control all

internal conversion cycles. The digital output data can be pre-

sented in straight binary or in twos complement format. An

out-of-range (OTR) signal indicates an overflow condition that

can be used with the most significant bit to determine low or

high overflow.

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

when the input signal is beyond the AD9244’s input range.

Single Supply—The AD9244 uses a single 5 V power

supply, simplifying system power supply design. It also

features a separate digital output driver supply to accom-

modate 3.3 V and 5 V logic families.

Fabricated on an advanced CMOS process, the AD9244 is

available in a 48-lead low profile quad flatpack package (LQFP)

and is specified for operation over the industrial temperature

range (–40°C to +85°C).
