PRODUCT DESCRIPTION
The AD9226 is a monolithic, single-supply, 12-bit, 65 MSPS
analog-to-digital converter with an on-chip, high-performance
sample-and-hold amplifier and voltage reference. The AD9226
uses a multistage differential pipelined architecture with a pat-
ented input stage and output error correction logic to provide
12-bit accuracy at 65 MSPS data rates. There are no missing
codes over the full operating temperature range (guaranteed).
The input of the AD9226 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 sample-and-hold amplifier (SHA) is well suited for IF
undersampling schemes such as in single-channel communi-
cation applications with input frequencies up to and well
beyond Nyquist frequencies.
The AD9226 has an on-board programmable reference. For sys-
tem design flexibility, an external reference can also be chosen.
A single clock input is used to control all internal conversion
cycles. An out-of-range signal indicates an overflow condition
that can be used with the most significant bit to determine low
or high overflow.
The AD9226 has two important mode functions. One will set
the data format to binary or two’s complement. The second will
make the ADC immune to clock duty cycle variations.
PRODUCT HIGHLIGHTS
IF Sampling
—The patented SHA input can be configured for
either single-ended or differential inputs. It will maintain out-
standing AC performance up to input frequencies of 300 MHz.
Low Power
—The AD9226 at 475 mW consumes a fraction of
the power presently available in existing, high-speed monolithic
solutions.
Out of Range (OTR)
—The OTR output bit indicates when
the input signal is beyond the AD9226’s input range.
Single Supply
—The AD9226 uses a single 5 V power supply
simplifying system power supply design. It also features a sepa-
rate digital output driver supply line to accommodate 3 V and
5 V logic families.
Pin Compatibility
—The AD9226 is similar to the AD9220,
AD9221, AD9223, AD9224, and AD9225 ADCs.
Clock Duty Cycle Stabilizer
—Makes conversion immune to
varying clock pulsewidths.
