Overview
The AD9200ARS 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 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 a 3 V supply. It includes a built-in clamp function for DC restoration, an out-of-range indicator, and three-state outputs.
Feature Summary
- Features a built-in clamp circuit specifically designed for DC restoration of video or AC-coupled signals.
- Includes an out-of-range (OTR) indicator bit to signal overflow conditions relative to the input range.
- Supports flexible reference configurations including internal bandgap, external divider, or external reference sources.
- Provides pin compatibility with the legacy AD876 component to facilitate design migration.
Applications
- Video signal processing requiring DC restoration capabilities
- High-speed portable instrumentation systems
- Imaging and communications receiver front-ends
Procurement Notes
Verify that the specific part number suffix matches the required industrial temperature grade (-40°C to +85°C). Confirm package type is 28-lead SSOP. Ensure ESD precautions are observed during handling as the device is sensitive to electrostatic discharge. Cross-reference ordering guides for reel options if automated assembly is planned.
Selection Notes
Select this model when industrial temperature operation is mandatory compared to the commercial J-series variant. Consider the integrated clamp feature if AC coupling is used in the application. Verify power supply constraints fit within the 2.7 V to 5.5 V range. Evaluate if the 10-bit resolution and 20 MSPS speed meet system bandwidth requirements.
Part Context
The AD9200ARS belongs to the AD9200 family of CMOS A/D converters from Analog Devices. It shares the same core architecture and pinout as the AD9200JRS but differs in the specified operating temperature range. The 'ARS' designation indicates the industrial grade version housed in a 28-lead SSOP package.
Replacement Considerations
The AD9200JRS serves as a commercial-grade alternative with identical electrical specifications but a limited 0°C to +70°C range. The AD876 is the legacy pin-compatible predecessor, though it typically requires higher supply voltages.
