AD9203WARUZRL7

Overview

The AD9203WARUZRL7 is a monolithic, low-power, single-supply 10-bit analog-to-digital converter (ADC) qualified for automotive applications. It operates with a sampling rate of up to 40 MSPS and supports an analog supply voltage range from 2.7 V to 3.6 V. The device features a multistage differential pipeline architecture that guarantees no missing codes across the full industrial temperature range of −40°C to +85°C. Power consumption is rated at 74 mW at maximum speed on a 3 V supply, reducible to 17 mW at 5 MSPS or 0.65 mW in standby mode. It includes an adjustable internal voltage reference, an out-of-range indicator, and accepts input spans between 1 V and 2 V p-p.

Feature Summary

• Automotive qualification supporting quality and reliability requirements for vehicle systems.
• Adjustable power consumption via external resistor control for lower sampling rates.
• Built-in clamp function enabling DC restoration for video signal processing.
• Integrated programmable voltage reference with options for external reference selection.

Applications

• Automotive sensor interfaces
• Video signal processing
• IF undersampling

Procurement Notes

Verify the specific ordering suffix RL7 indicates reel packaging when sourcing components. Confirm that the W suffix denotes automotive qualification status required for the target application environment. Ensure the RU-28 package option matches the PCB footprint design constraints. Cross-reference the datasheet revision to confirm current specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring automotive-grade certification alongside low power dissipation. Evaluate the 1 V to 2 V p-p input span against the source signal amplitude to ensure compatibility. Consider the 5.5 clock cycle pipeline delay when designing timing-critical digital logic. Verify that the 28-lead TSSOP package fits within the available board space constraints.

Part Context

This part belongs to the AD9203 family of high-speed ADCs manufactured by Analog Devices Inc. The WARUZRL7 designation specifies the automotive grade variant packaged in tape and reel format. It shares the core pipeline architecture with commercial counterparts but adheres to stricter manufacturing controls for automotive reliability standards.

Replacement Considerations

The AD9203WARUZ is the tube-packaged equivalent of this reel-based component. Both share identical electrical characteristics and pinouts. Designers should verify that the change in packaging does not impact automated assembly processes or storage requirements.
