AD9200JRS

Overview

The AD9200JRS is a monolithic, single-supply, 10-bit analog-to-digital converter featuring a 20 MSPS sampling rate and an on-chip sample-and-hold amplifier. It utilizes a multistage differential pipeline architecture to guarantee no missing codes across its operating temperature range of 0°C to +70°C. The device operates within a supply voltage range of 2.7 V to 5.5 V, consuming 80 mW at a 3 V supply. It supports both single-ended and differential analog inputs and offers configurable internal or external reference options.

Feature Summary

• Multistage differential pipeline architecture ensures high-speed conversion with low power consumption.
• Configurable analog input stage supports single-ended or differential driving modes for flexible system integration.
• Integrated sample-and-hold amplifier and adjustable on-chip voltage reference simplify circuit design.
• Out-of-range indicator provides overflow detection capability for signal monitoring.

Applications

• Imaging systems requiring direct sampling capabilities
• Communications equipment utilizing IF undersampling techniques
• Instrumentation applications needing low-power ADC solutions

Procurement Notes

Verify the specific suffix 'JRS' corresponds to the commercial temperature grade (0°C to +70°C) and SSOP-28 package configuration. Confirm that the ordering part number matches the exact revision required for your schematic compatibility. Ensure all electrical parameters align with your system's voltage and timing constraints before finalizing procurement.

Selection Notes

Select this component when a 10-bit resolution at 20 MSPS is sufficient for the application bandwidth. Consider the AD9200JRS for designs requiring pin compatibility with legacy AD876 components while transitioning to lower supply voltages. Evaluate the need for differential versus single-ended input configurations based on the source impedance and noise environment of the analog signal chain.

Part Context

The AD9200 series represents Analog Devices' entry-level high-speed CMOS ADCs designed for portable and battery-operated applications. The JRS variant specifically denotes the commercial temperature range version housed in a shrink small outline package. This family bridges the gap between general-purpose converters and specialized high-performance data acquisition devices.

Replacement Considerations

The AD9200 is explicitly documented as pin-compatible with the AD876, allowing for direct socket migration in existing designs. No other substitute part numbers are confirmed in the provided documentation.
