AD976BR

Analog To Digital Converters (ADC) Overview

The AD976BR is a 16-bit, 100 kSPS analog-to-digital converter (ADC) manufactured by Analog Devices. It utilizes a switched-capacitor successive approximation architecture and operates from a single +5 V supply with a maximum power dissipation of 100 mW. The device features a parallel interface, an internal 2.5 V reference, and on-chip clocking. Key electrical specifications include a throughput rate of 100 kSPS, a signal-to-noise plus distortion ratio (S/(N+D)) of 85 dB, and a full-scale input range of ±10 V. It is housed in a 28-lead Small Outline Integrated Circuit (SOIC) package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade and package suffix to ensure compatibility with design requirements. Confirm that the component meets all necessary environmental and safety standards for the intended application before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 16-bit resolution at moderate sampling speeds. Ensure the system can accommodate the ±10 V input range and single-supply voltage constraints. Verify interface timing requirements against the parallel bus specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD976/AD976A family of 16-bit ADCs. The AD976 variant offers 100 kSPS throughput, while the AD976A provides 200 kSPS. Both share similar architectural features but differ in speed and specific AC performance metrics.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the AD976AR (A-grade) or AD976CR (C-grade). For higher speed requirements, consider the AD976ABR or AD976ACR variants which offer 200 kSPS throughput.

Analog To Digital Converters (ADC) FAQ

What is the data format of the AD976BR output?

The AD976BR outputs data in Binary Twos Complement format.

How is the BYTE pin used?

The BYTE pin allows the 16-bit data to be read as two separate 8-bit bytes on different pins, facilitating easier interfacing with 8-bit microcontrollers.

What is the typical Integral Nonlinearity (INL) error?

For the B-grade AD976BR, the typical Integral Nonlinearity error is -2 LSB.
