The digital output data is presented in offset binary, Gray code, or

twos complement formats. A data output clock (DCO) is provided

to ensure proper latch timing with receiving logic.

The AD9233 is available in a 48-lead LFCSP and is specified

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

GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD9233 is a monolithic, single 1.8 V supply, 12-bit, 80 MSPS/

105 MSPS/125 MSPS analog-to-digital converter (ADC), featuring

a high performance sample-and-hold amplifier (SHA) and on-

chip voltage reference. The product uses a multistage differential

pipeline architecture with output error correction logic to

provide 12-bit accuracy at 125 MSPS data rates and guarantees

no missing codes over the full operating temperature range.

1. The AD9233 operates from a single 1.8 V power supply

and features a separate digital output driver supply to

accommodate 1.8 V to 3.3 V logic families.

2. The patented SHA input maintains excellent performance

for input frequencies up to 225 MHz.

The wide bandwidth, truly differential SHA allows a variety of

user-selectable input ranges and offsets, including single-ended

applications. It is suitable for multiplexed systems that switch

full-scale voltage levels in successive channels and for sampling

single-channel inputs at frequencies well beyond the Nyquist rate.

Combined with power and cost savings over previously available

ADCs, the AD9233 is suitable for applications in communications,

imaging, and medical ultrasound.

3. The clock DCS maintains overall ADC performance over a

wide range of clock pulse widths.

4. A standard serial port interface supports various product

features and functions, such as data formatting (offset

binary, twos complement, or Gray coding), enabling the

clock DCS, power-down, and voltage reference mode.

5. The AD9233 is pin compatible with the AD9246, allowing

a simple migration from 12 bits to 14 bits.

A differential clock input controls all internal conversion cycles. A

duty cycle stabilizer (DCS) compensates for wide variations in the

clock duty cycle while maintaining excellent overall ADC

performance.
