Overview
The AD9049BR is a complete 9-bit monolithic sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features an onboard track-and-hold circuit and reference, supporting a sampling rate of 30 MSPS. The device utilizes a two-step architecture with one input, accepting differential or single-ended signals. It operates on a digital supply voltage ranging from 4.75V to 5.25V. The component is housed in a 28-SOIC surface-mount package.
Feature Summary
- Integrates a 9-bit monolithic sampling ADC with onboard track-and-hold and reference
- Supports high-speed conversion at 30 MSPS using a two-step architecture
- Accepts both differential and single-ended input types
Applications
- Automation systems requiring fast analog signal conversion
- Internet of Things (IoT) devices needing accurate data acquisition
- General-purpose data acquisition applications
Procurement Notes
Verify the specific suffix 'BR' indicates the SOIC-28 package variant when ordering. Confirm that the application requires a 9-bit resolution and 30 MSPS sampling rate, as higher precision or speed variants exist within the family. Ensure power supply rails match the specified 4.75V to 5.25V range for proper operation.
Selection Notes
Select this component when a 9-bit resolution and 30 MSPS throughput are sufficient for the system requirements. Consider the integrated reference and track-and-hold capabilities to simplify external circuit design. Evaluate the 28-SOIC package constraints against available board space and thermal management needs compared to other package options.
Part Context
The AD9049BR belongs to the AD9049 series of analog-to-digital converters from Analog Devices. This series provides complete sampling ADC solutions with integrated support circuits. The BR suffix specifically denotes the 28-SOIC surface-mount package version, distinguishing it from other physical form factors available within the same functional family.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source documentation. Verify compatibility with existing system interfaces and performance requirements before considering alternative components.
