Overview
The AD876JST-REEL is a CMOS, 10-bit, 20 MSPS analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a multistage pipelined architecture with output error correction logic and an on-chip sample-and-hold amplifier. The device operates on a single +5 V supply with power dissipation of 160 mW. It offers three-state outputs compatible with +5 V or +3.3 V logic and includes adjustable reference inputs. The component is housed in a 48-lead Thin Quad Flatpack (TQFP) package and is specified for commercial temperature ranges from 0°C to +70°C.
Feature Summary
- Multistage pipelined architecture with output error correction logic ensures accurate performance and guarantees no missing codes across the operating temperature range.
- On-chip sample-and-hold amplifier simplifies driving requirements for high-speed applications.
- Adjustable reference input with force and sense connections minimizes external voltage drops.
- Digital I/O interfaces are compatible with both +5 V and +3.3 V logic families.
Applications
- Video and multimedia systems
- Imaging systems including color scanners, digital copiers, electronic still cameras, and camcorders
- High-speed data acquisition systems
- Communications equipment
Procurement Notes
Verify the specific ordering suffix 'REEL' indicates tape and reel packaging when sourcing components. Confirm that the J suffix corresponds to the commercial temperature range of 0°C to +70°C. Ensure compatibility with the 48-lead TQFP footprint during procurement planning.
Selection Notes
Select this component for designs requiring 10-bit resolution at 20 MSPS with low power consumption. Consider the pin-compatible 8-bit option if prototype results allow for migration to lower resolution. Evaluate the need for external reference circuits based on required accuracy and cost constraints.
Part Context
The AD876 series provides a space-saving solution for high-speed data conversion. It is available in 28-lead SOIC, 28-lead SSOP, and 48-lead TQFP packages. The device is designed to satisfy requirements for portable applications due to its low power and single-supply operation capabilities.
Replacement Considerations
The AD9200 is a pin-compatible alternative offering similar 10-bit, 20 MSPS performance with lower power dissipation of 80 mW. Verify interface compatibility and power supply requirements when considering substitution.
