AD9203ARU

Overview

The AD9203ARU is a monolithic, low-power, single-supply 10-bit analog-to-digital converter manufactured by Analog Devices Inc. It operates at a maximum sampling rate of 40 MSPS with a power dissipation of 74 mW on a 3 V supply. The device features a multistage differential pipeline architecture and guarantees no missing codes across the full operating temperature range. It includes an onboard programmable voltage reference with an adjustable input range from 1 V to 2 V peak-to-peak. The component supports both differential and single-ended inputs and is housed in a 28-lead TSSOP package.

Feature Summary

• Multistage differential pipeline architecture ensures high-speed conversion without missing codes.
• Onboard programmable voltage reference allows flexible input span adjustment between 1 V and 2 V p-p.
• Built-in clamp function enables DC restoration for video signals in single-ended configurations.
• Adjustable power consumption via external resistor control for optimized efficiency at lower sample rates.

Applications

• CCD imaging systems
• Video signal processing
• Portable instrumentation
• IF and baseband communications
• Medical ultrasound

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature rating. Ensure compatibility with system voltage requirements and interface logic levels before integration. Cross-reference datasheet revisions to validate performance specifications against the intended application environment.

Selection Notes

Select this component for applications requiring low power consumption alongside moderate resolution and speed. Consider the internal reference capabilities if external precision references are not available. Evaluate the single-ended versus differential input configurations based on noise immunity requirements and available drive sources.
