AD9200ARSRL

Overview

The AD9200ARSRL is a monolithic, single-supply, 10-bit, 20 MSPS CMOS analog-to-digital converter featuring an on-chip sample-and-hold amplifier and voltage reference. It utilizes a multistage differential pipeline architecture to guarantee no missing codes across the industrial temperature range of –40°C to +85°C. The device operates with supply voltages between 2.7 V and 5.5 V, consuming 80 mW at 3 V. Key specifications include a differential nonlinearity of 0.5 LSB, a signal-to-noise ratio of 57 dB at 3.58 MHz, and a full power bandwidth of 300 MHz. It supports IF undersampling up to 135 MHz and includes features such as a built-in clamp function for DC restoration and an out-of-range indicator.

Feature Summary

• Multistage differential pipeline architecture ensures high-speed conversion without missing codes.
• On-chip sample-and-hold amplifier supports both single-ended and differential input configurations.
• Built-in clamp circuit enables DC restoration for AC-coupled video signals.
• Out-of-range indicator provides overflow detection using the most significant bit.

Applications

• Imaging systems requiring low-power analog-to-digital conversion
• Communications systems utilizing IF undersampling techniques
• Video signal processing applications needing DC restoration

Procurement Notes

Verify that the ordering suffix RL indicates reel packaging when sourcing this component. Confirm the J or AR suffix corresponds to the required industrial temperature range of –40°C to +85°C. Ensure compatibility with the 28-lead SSOP package form factor. Cross-reference the manufacturer's current datasheet revision to validate pinout and electrical specifications against your design requirements.

Selection Notes

Select this component for designs requiring a pin-compatible replacement for the AD876 with lower supply voltage operation. Choose the AD9200ARSRL when industrial temperature stability is mandatory. Consider the internal reference options if external precision references are not desired. Evaluate the 300 MHz input bandwidth against the Nyquist rate of the target signal frequency.

Part Context

This part belongs to the AD9200 family of complete 10-bit CMOS A/D converters from Analog Devices. It is pin-compatible with the legacy AD876, facilitating migration to lower voltage supplies. The AR variant specifically denotes the industrial temperature grade housed in a 28-lead SSOP package, distinguishing it from commercial grade or LQFP package alternatives within the same series.

Replacement Considerations

The AD9200ARS is the tube-packaged equivalent of this reel-delivered part. The AD876 serves as a legacy pin-compatible predecessor, though it requires higher supply voltages. Other family members like the AD9200JRS offer commercial temperature ranges in identical packages.
