AD876JR-REEL

Overview

The AD876JR-REEL is a monolithic, single-supply, 10-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates at a sampling rate of 20 MSPS with a pipeline architecture and accepts single-ended inputs. The device requires external 5 V analog and digital power supplies and features a parallel interface for data output. Key electrical specifications include a signal-to-noise ratio (SNR) of 56 dB, differential nonlinearity (DNL) of +/- 1 LSB, integral nonlinearity (INL) of +/- 1 LSB, and a gain error of 0.2% FSR. Power dissipation is rated at 160 mW, and it functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• 10-bit resolution with 20 MSPS sampling speed using a pipeline structure
• Single-ended input configuration with parallel digital output interface
• Low power consumption of 160 mW with 5 V supply requirements
• High linearity performance with +/- 1 LSB DNL/INL and 56 dB SNR

Applications

• Imaging systems requiring high-speed analog-to-digital conversion
• Communications systems utilizing undersampling techniques
• Multiplexed data acquisition systems switching full-scale voltage levels
• Portable applications necessitating low-power, high-speed ADCs

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'JR' corresponds to the required package variant and temperature grade. Check current lifecycle status as older components may be subject to obsolescence or discontinuation notices from Analog Devices.

Selection Notes

Select this component when a single-channel, 10-bit, 20 MSPS ADC with single-ended inputs is required. Ensure the system design accommodates 5 V dual-supply operation and parallel interface timing constraints. Consider thermal management for the 160 mW power dissipation in the TQFP-48 package if operating near the upper temperature limit.

Part Context

The AD876 belongs to the AD876 series of complete CMOS A/D converters. It is pin-compatible with other devices in the family, such as the AD9200, though power consumption and supply voltage ranges may differ. The 'JR' suffix typically denotes a specific tape-and-reel packaging option for surface-mount assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before considering alternative ADCs, as interface protocols and pinouts may vary across different manufacturers or even within the same product family.
