AD9226:  12-Bit, 65 MSPS Analog-to-Digital Converter

Product Details


The AD9226 is a monolithic, single supply, 12-bit, 65Msps, analog-to-digital converter with an on-chip high performance sample and hold amplifier and voltage reference. It uses a multistage differential pipeline architecture at 65 MSPS data rate and guarantees no missing codes over the full operating temperature range.

The ADC combines a low cost, high-speed CMOS process and a novel architecture to achieve the resolution and speed of existing bipolar implementations at a fraction of the power consumption cost.

The input of the AD9226 allows for easy interfacing to both imaging, ultrasound and communication systems. With a truly differential input structure, the user can select a variety of input ranges and offsets including single-ended applications. The dynamic performance is excellent.

The sample-and-hold amplifier is well suited for both multiplexed systems that switch full-scale voltage levels in successive channels and sampling single-channel inputs at frequencies up to and well beyond the Nyquist rate.

Fabricated on an advanced CMOS process, the AD9226 is available in a 28-pin thin shrink small outline package (28 TSSOP) and in a 48-pin thin quad flat pack (48-LQFP) specified over the industrial temperature range (-40°C to +85°C).

How Ultrasound System Considerations Influence Front-End Component Choice
There are major trade-offs to be considered when designing ultrasound front-end circuits. Performance parameters in the front-end circuit components affect diagnostic performance—and conversely, system configuration and objectives affect the choice of components.
