AD976ACN

Analog To Digital Converters (ADC) Overview

The AD976ACN 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 parallel interface with an internal 2.5 V reference. The device utilizes a switched-capacitor successive approximation architecture and is factory calibrated to minimize linearity errors. Key specifications include a ±10 V input range, 100 mW maximum power dissipation, and an operating temperature range of -40°C to +85°C. It is housed in a 28-lead plastic DIP package.

• High-speed 16-bit resolution with 200 kSPS throughput rate
• Single +5 V supply operation with low power consumption
• Integrated 2.5 V reference and on-chip clock generation
• Factory calibrated for minimized integral and differential nonlinearity

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high accuracy
• Data acquisition modules for sensor signal conditioning
• Test and measurement equipment interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade (A, B, or C) required for your application, as performance metrics like Signal-to-(Noise+Distortion) vary by grade. Confirm the package type matches your PCB footprint requirements. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing design-in decisions.

Analog To Digital Converters (ADC) Selection Notes

Select the AD976ACN when a 200 kSPS sampling rate is necessary for 16-bit precision. Ensure the system can accommodate a parallel data bus interface. Consider the AD976A variant if higher speed is needed, or the standard AD976 if 100 kSPS suffices. Verify that the ±10 V input range aligns with the source signal levels.

Analog To Digital Converters (ADC) Part Context

The AD976ACN belongs to the AD976/AD976A family of BiCMOS A/D converters. This series combines high-performance bipolar devices with CMOS technology. The 'C' denotes the performance grade, while 'AN' indicates the 28-lead PDIP package. It serves as a complete A/D solution integrating the converter, reference, and clock.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include AD976ABN and AD976BBN. These variants share the same package and interface but differ in AC performance grades. Ensure the substitute meets the specific SNR and THD requirements of the original design.
