AD9240ASZ

Analog To Digital Converters (ADC) Overview

The AD9240ASZ 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 features an on-chip sample-and-hold amplifier and voltage reference. The device utilizes a multistage differential pipelined architecture with digital output error correction logic to guarantee no missing codes across the full operating temperature range. It accepts differential or single-ended analog inputs and provides straight binary digital outputs compatible with +3 V and +5 V CMOS logic families.

Analog To Digital Converters (ADC) Feature Summary

• Monolithic integration of a 14-bit ADC, high-performance low-noise sample-and-hold amplifier, and programmable voltage reference within a single chip.
• Flexible analog input structure supporting both differential and single-ended configurations with varying input spans.
• Digital output buffers configurable for direct interfacing with +3 V and +5 V CMOS logic families.
• Out-of-range indicator signal provided to detect overflow conditions relative to the conversion range.

Analog To Digital Converters (ADC) Applications

• Direct-IF down conversion in communication systems
• Imaging and medical data acquisition systems
• Multiplexed data acquisition applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm that the package matches the 44-lead MQFP specification and check for RoHS compliance status. Ensure the ordering suffix corresponds to the required tape and reel or tray packaging format as specified in the manufacturer's catalog.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a complete 14-bit resolution at 10 MSPS is required with low power consumption. Consider the flexible input span options and the ability to use either internal or external voltage references based on accuracy requirements. Evaluate the pipeline latency of three clock cycles against system timing constraints.

Analog To Digital Converters (ADC) Part Context

The AD9240ASZ belongs to the AD9240 family of high-speed analog-to-digital converters. This series is designed to provide hybrid-level performance using a cost-effective CMOS process. The ASZ suffix indicates a specific lead-free and RoHS-compliant variant of the standard AD9240 device, housed in a Metric Quad Flatpack.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the Analog Devices product selector guide for pin-compatible or functionally equivalent alternatives within the AD924x series. Verify that any substitute maintains the 14-bit resolution and 10 MSPS sampling rate while matching the 44-lead MQFP package dimensions.
