AD976ABR

Analog To Digital Converters (ADC) Overview

The AD976ABR is a 16-bit, 200 kSPS analog-to-digital converter (ADC) from Analog Devices. It operates on a single +5 V supply and features a ±10 V input range with BiCMOS architecture. The device integrates a successive approximation switched capacitor ADC, an internal 2.5 V reference, and a high-speed parallel interface. Key specifications include a typical Signal-to-(Noise + Distortion) ratio of 85 dB, integral linearity error of ±3 LSB, and differential linearity error of ±2 LSB. It dissipates a maximum of 100 mW and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit successive approximation switched capacitor ADC with factory calibration for minimized linearity errors.
• Features a high-speed parallel interface with on-chip clock generation and byte-select capability for flexible data reading.
• Includes an internal 2.5 V reference voltage source or supports external reference inputs for specified linearity.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution analog signal acquisition.
• Data acquisition modules interfacing directly with microcontrollers or digital signal processors.
• Precision measurement instruments utilizing standard bipolar input ranges.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade (B-Grade) and package type (SOIC-28) when sourcing. Confirm that the ordering suffix matches the required throughput rate of 200 kSPS. Ensure compatibility with single 5 V supply requirements and check for ESD sensitivity handling during procurement and storage.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications demanding 16-bit resolution at moderate sampling rates. Compare performance against the AD976AANZ if through-hole packaging is preferred. Consider the integrated reference and low power dissipation as advantages over discrete solutions requiring external components for biasing and timing.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD976/AD976A family of fast 16-bit ADCs. The 'AB' designation indicates the B-Grade performance level with an 85 dB S/(N+D) specification. The 'R' suffix denotes the 28-Lead Small Outline Package. It serves as a higher-speed variant compared to the standard AD976 series, offering 200 kSPS throughput.
