AD9244BSTZRL-40

Overview

The AD9244BSTZRL-40 is a monolithic, single 5 V supply, 14-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates at a maximum sampling rate of 40 MSPS and features an on-chip high-performance sample-and-hold amplifier (SHA) and voltage reference. The device utilizes a multistage differential pipelined architecture with output error correction logic to ensure 14-bit accuracy and guarantees no missing codes over the full operating temperature range of –40°C to +85°C. It accepts a 1 V to 2 V p-p differential full-scale analog input range and provides straight binary or twos complement digital outputs in a 48-lead LQFP package.

Feature Summary

• Multistage differential pipelined architecture with output error correction logic for 14-bit accuracy
• On-chip programmable voltage reference and high-performance sample-and-hold amplifier
• Out-of-range indicator signal for overflow detection
• Clock duty cycle stabilizer and output-enable function

Applications

• Communication subsystems including microcell and picocell applications
• Medical imaging equipment
• High-end imaging systems
• Test and measurement equipment

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Ensure compatibility with system power requirements, specifically the single 5 V analog supply and separate digital driver supply options. Confirm that the selected variant meets the required industrial temperature range and performance specifications for the intended application environment.

Selection Notes

Select this component when a 14-bit resolution and 40 MSPS sampling rate are required within a single-supply design. Consider the internal reference capabilities if external precision references are not desired. Evaluate the pin compatibility with existing designs using the AD9226 if migration from 12-bit architectures is planned. Verify analog input bandwidth and dynamic performance metrics against system signal requirements.

Part Context

The AD9244 belongs to the Analog Devices family of high-speed, high-resolution data converters. It is designed to bridge the gap between lower resolution devices and higher speed ADCs, offering a balance of performance and power consumption. The device is fabricated on an advanced CMOS process, ensuring reliability and consistent performance across various industrial and commercial applications.

Replacement Considerations

The AD9244 offers pin-compatible migration from the 12-bit, 65 MSPS AD9226. Designers upgrading from the AD9226 can utilize the same footprint while gaining increased resolution and improved dynamic performance without significant board layout changes.
