AD9200JST

Overview

The AD9200JST 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 on supply voltages between 2.7 V and 5.5 V, consuming 80 mW at 3 V. It supports both single-ended and differential input configurations with adjustable internal or external voltage references.

Feature Summary

• Multistage differential pipeline architecture for high-speed conversion
• On-chip sample-and-hold amplifier and voltage reference
• Configurable for single-ended or differential analog inputs
• Out-of-range indicator and three-state digital outputs

Applications

• Imaging systems development
• Communications systems
• Portable instrumentation

Procurement Notes

Verify the specific package type and temperature grade when sourcing. Confirm that the ordering suffix matches the required LQFP form factor and commercial temperature range specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring low power consumption alongside moderate resolution. Ensure the system design accommodates the 48-lead LQFP package dimensions and provides adequate decoupling for the reference pins to maintain dynamic performance.

Part Context

This model belongs to the AD9200 family of CMOS A/D converters. It shares architectural similarities with other members but is distinguished by its 48-lead LQFP package and commercial temperature rating, offering pin compatibility with legacy designs like the AD876.

Replacement Considerations

The AD9200JRS serves as a pin-compatible alternative in a 28-lead SSOP package. Verify that the reduced physical footprint meets the PCB layout requirements without compromising signal integrity.
