AD976ARS

Analog To Digital Converters (ADC) Overview

The AD976ARS is a 16-bit, 100 kSPS analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single +5 V supply and dissipates a maximum of 100 mW. The device features a switched capacitor architecture with an internal 2.5 V reference and a high-speed parallel interface. It accepts a bipolar ±10 V analog input range and provides data in Binary Twos Complement format. The component is housed in a 28-lead Shrink Small Outline Package (SSOP).

Analog To Digital Converters (ADC) Feature Summary

• Integrates a successive approximation switched capacitor ADC with factory calibration to minimize linearity errors.
• Operates on a single 5 V power supply with low power consumption of 100 mW maximum.
• Includes an onboard 2.5 V reference source and supports external reference options.
• Features a high-speed parallel digital interface compatible with microcontrollers and DSPs.

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring 16-bit resolution.
• Industrial process control instrumentation.
• Portable battery-powered test equipment.
• Chemical analysis solutions.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade (A, B, or C) required for your application, as performance metrics like Spurious Free Dynamic Range vary between grades. Confirm that the SSOP package variant matches your PCB footprint requirements. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS/BiCMOS circuitry.

Analog To Digital Converters (ADC) Selection Notes

Select the AD976ARS for applications requiring 100 kSPS throughput; use the AD976A series variants if 200 kSPS speed is necessary. Consider the A-grade version for higher dynamic range specifications. Verify that the ±10 V input range aligns with your signal conditioning circuitry without additional scaling.

Analog To Digital Converters (ADC) Part Context

The AD976ARS belongs to the AD976/AD976A family of BiCMOS A/D converters. This series combines high-performance bipolar devices with CMOS transistors. The 'R' suffix denotes the SOIC package style, while 'S' indicates the Shrink Small Outline Package (SSOP). The AD976 model specifically offers 100 kSPS throughput compared to the 200 kSPS rate of the AD976A.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include AD976BRS and AD976CRS, which share the 100 kSPS throughput and SSOP package but differ in AC accuracy grades.
