AD9203ARUZRL7

Overview

The AD9203ARUZRL7 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 over the full operating temperature range. It supports an input voltage range of 1 V to 2 V p-p in either differential or single-ended configurations. Power consumption can be adjusted via an external resistor for lower sample rates, reducing power to 17 mW at 5 MSPS. The component includes an onboard programmable voltage reference, an out-of-range indicator, and an internal clamp circuit for video signal processing.

Feature Summary

• Multistage differential pipeline architecture ensures high-speed conversion while maintaining low power consumption.
• Onboard programmable voltage reference allows selection between internal settings or external reference inputs.
• Internal clamp function enables DC restoration for video signals when operating in single-ended mode.
• Adjustable power control via external resistor reduces energy usage during operation at reduced sampling rates.

Applications

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

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to tape and reel packaging requirements before purchase. Confirm that the industrial temperature range (-40°C to +85°C) aligns with your system's environmental specifications. Ensure the 28-lead TSSOP package dimensions fit within your PCB layout constraints. Check for any recent product change notices regarding wire material conversions or manufacturing site updates.

Selection Notes

Select this component when a balance of moderate resolution and high speed is required for portable applications. Consider the adjustable power feature if your design operates significantly below the 40 MSPS maximum rate. Evaluate the need for the internal clamp function if processing video signals directly. Verify that the 2.7 V to 3.6 V supply range matches your available power rails.

Part Context

The AD9203ARUZRL7 belongs to the AD9203 family of high-speed data converters from Analog Devices. This series is designed for applications requiring efficient analog-to-digital conversion with minimal power draw. The ARUZ suffix indicates the specific package type and temperature grade, while the RL7 denotes the reel packaging format used for automated assembly processes.

Replacement Considerations

Direct replacements must maintain the 10-bit resolution, 40 MSPS sampling rate, and 28-TSSOP package. Verify compatibility with existing clocking and reference circuits. Cross-reference pinouts to ensure functional equivalence without redesigning the host board.
