APPLICATIONS

Fabricated on an advanced CMOS process, the AD9244 is

available in a 48-lead LQFP and is specified for operation over

the industrial temperature range (–40°C to +85°C).

Communication subsystems (microcell, picocell)

Medical and high-end imaging equipment

Test and measurement equipment

PRODUCT HIGHLIGHTS

1. Low Power—The AD9244, at 550 mW, consumes a fraction

of the power of currently available ADCs in existing high

speed solutions.

GENERAL DESCRIPTION

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

40 MSPS/65 MSPS ADC with an on-chip, high performance

sample-and-hold amplifier (SHA) and voltage reference.

2. IF Sampling—The AD9244 delivers outstanding

performance 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.

3. Pin Compatibility—The AD9244 offers a seamless

migration from the 12-bit, 65 MSPS AD9226.

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

input can be configured for either single-ended or

differential inputs.

5. Out-of-Range (OTR) Indicator—The OTR output bit

indicates when the input signal is beyond the AD9244’s

input range.

6. 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

accommodate 3.3 V and 5 V logic families.

The AD9244 uses a multistage differential pipelined architec-

ture 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.

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.

A differential or single-ended clock input controls all internal

conversion cycles. The digital output data can be presented 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.
