The AD9244 is a monolithic, single 5 V supply, 14-bit, 65 MSPS analog-to-digital converter with an on-chip, high performance, sample and hold amplifier and voltage reference. The AD9244 uses a multi-stage differential pipelined architecture with output error correction logic to provide 14-bit accuracy at 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 chosen to suit the DC accuracy and temperature drift requirements of the application.
A differential clock input is used to control 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, which can be used with the most significant bit to determine low or high overflow.
Fabricated on an advanced CMOS process, the AD9244 is available in a 48 pin surface mount plastic package (48-LQFP) and is specified for operation over the industrial temperature range of (-40°C to +85°C).

Evaluation Kits (1)
The high speed ADC FIFO evaluation kit includes the latest version of ADC Analyzer and a buffer memory board to capture blocks of digital data from the Analog Devices, Inc., high speed analog-to-digital converter (ADC) evaluation boards. The FIFO board is connected to the PC through a USB port and is used with ADC Analyzer to quickly evaluate the performance of high speed ADCs. Users can view an FFT for a specific analog input and encode rate to analyze SNR, SINAD, SFDR, and harmonic information.
The evaluation kit is easy to set up. Additional equipment needed includes an Analog Devices high speed ADC evaluation board, a signal source, and a clock source. Once the kit is connected and powered, the evaluation is enabled instantly on the PC.
The HSC-ADC-EVALB-DCZ can be used with single and multichannel ADCs and converters with demultiplexed digital outputs.

Tools & Simulations
Virtual Eval - BETA
Virtual Eval is a web application to assist designers in product evaluation of ADCs, DACs, and other ADI products. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, response plots, and more.
AD9244 IBIS Models
For designers who are selecting or evaluating high speed ADCs, VisualAnalog™ is a software package that combines a powerful set of simulation and data analysis tools with a user-friendly graphical interface.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
