AD876JR-8

Overview

The AD876JR-8 is a CMOS, 10-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a sampling rate of 20 MSPS with a power dissipation of 160 mW. It 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. The device features an on-chip input sample-and-hold amplifier and supports single +5 V supply operation. Digital I/Os are compatible with both +5 V and +3.3 V logic levels, and it includes three-state outputs for flexible interfacing.

Feature Summary

• CMOS 10-bit resolution with 20 MSPS sampling speed
• Multistage pipelined architecture with output error correction
• Guaranteed no missing codes over full operating temperature range
• On-chip input sample-and-hold amplifier

Applications

• High-speed data acquisition systems
• Video signal processing
• Instrumentation requiring precise analog-to-digital conversion

Part Context

The AD876JR-8 belongs to the AD876 series of high-speed ADCs. It is available in multiple package options including 28-Lead SOIC, 28-Lead SSOP, and 48-Lead Thin Quad Flatpack (TQFP). The 'JR-8' suffix typically denotes a specific package and temperature grade variant within this family, often associated with industrial or commercial temperature ranges depending on the specific datasheet revision.

Replacement Considerations

Designers seeking alternatives should consider other 10-bit, 20 MSPS pipeline ADCs from Analog Devices, such as the AD9200, which offers similar performance characteristics. Compatibility checks regarding pinout, power consumption, and interface logic levels are necessary when substituting components.
