AD9240ASRL

Overview

The AD9240ASRL is a monolithic 14-bit, 10 MSPS analog-to-digital converter manufactured by Analog Devices Inc. It operates on a single +5 V supply and dissipates approximately 285 mW of power. The device features an on-chip sample-and-hold amplifier and a programmable voltage reference, supporting both differential and single-ended input configurations. It utilizes a multistage differential pipelined architecture with digital output error correction logic to ensure no missing codes across the operating temperature range. The component is housed in a 44-lead MQFP package.

Feature Summary

• Monolithic integration of a 14-bit ADC with an on-chip sample-and-hold amplifier and voltage reference.
• Multistage differential pipelined architecture with digital output error correction logic for guaranteed linearity.
• Flexible analog input structure supporting both single-ended and differential interfaces.
• Configurable digital outputs compatible with +3 V and +5 V CMOS logic families.

Applications

• Direct-IF down conversion in communication systems
• Imaging and data acquisition systems
• Medical instrumentation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and compliance status. Ensure the component matches the required pin configuration and thermal characteristics for the target application. Cross-reference the part number with current product change notifications to confirm assembly site and lifecycle status before procurement.

Selection Notes

Select this component when a high-resolution, low-power 14-bit ADC is required for single-supply applications. Consider the flexible input span options and the ability to interface with various logic families. Evaluate the thermal resistance and power dissipation requirements relative to the system's cooling capabilities. Verify that the clock frequency and input signal bandwidth align with the specified performance parameters.

Part Context

The AD9240ASRL belongs to the AD9240 family of high-speed, high-resolution analog-to-digital converters. This series is designed for applications requiring precise data conversion with low power consumption. The ASRL variant specifically denotes the tape and reel packaging format, distinguishing it from tray-packaged versions like the AD9240ASZ. The family shares core architectural features and electrical specifications.

Replacement Considerations

The AD9240ASZ is a direct replacement for the AD9240ASRL, offering identical electrical performance but in a tray package instead of tape and reel. Both parts share the same pinout and functionality. Verify that the packaging difference does not impact the automated assembly process or inventory handling procedures.
