AD876JR-8-REEL

Overview

The AD876JR-8-REEL is a CMOS analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a 10-bit resolution and a sampling rate of 20 MSPS, with a typical power dissipation of 160 mW under +5 V single-supply operation. The device integrates an on-chip input sample-and-hold amplifier and utilizes a multistage pipelined architecture with output error correction logic to ensure accurate performance and guarantee no missing codes across the full operating temperature range. Digital I/Os are compatible with both +5 V and +3.3 V logic levels.

Feature Summary

• 10-Bit Resolution at 20 MSPS Sampling Rate
• Integrated On-Chip Sample-and-Hold Amplifier
• Low Power Dissipation: 160 mW (+5 V Single Supply)
• Guaranteed No Missing Codes Over Full Temperature Range

Applications

• High-Speed Data Acquisition Systems
• Video Signal Processing
• Medical Imaging Equipment
• Industrial Control Systems

Procurement Notes

Verify that the suffix -REEL indicates tape-and-reel packaging when sourcing. Confirm the specific revision level matches design requirements. Ensure supply chain sources provide original manufacturer documentation to validate authenticity and lot traceability for production integration.

Selection Notes

Select this component for applications requiring high-speed conversion with low power consumption. The integrated sample-and-hold simplifies front-end circuit design. Verify that the +5 V supply voltage aligns with system power rails and that digital interface compatibility meets logic level requirements.

Part Context

This part belongs to the AD876 family of CMOS A/D converters from Analog Devices. It offers pin-compatible 8-bit options for cost-sensitive designs while maintaining similar form factors such as 28-Lead SOIC or SSOP packages.

Replacement Considerations

The AD9200 is a comparable 10-bit, 20 MSPS ADC with lower power consumption (80 mW). Other potential substitutes include devices from Fairchild Semiconductor such as the SPT7852 or SPT7861, which offer similar speed and resolution specifications.
