AD976ACRS

Analog To Digital Converters (ADC) Overview

The AD976ACRS is a 16-bit, high-speed analog-to-digital converter (ADC) fabricated on Analog Devices' proprietary BiCMOS process. It operates from a single +5 V supply and delivers a throughput rate of 200 kSPS. The device features an internal 2.5 V reference, on-chip clock, and a high-speed parallel interface with Binary Twos Complement data format. It supports a standard industrial analog input range of ±10 V and dissipates a maximum of 100 mW. The component is housed in a 28-lead Shrink Small Outline Package (SSOP) and is specified for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a successive approximation switched capacitor ADC with factory calibration to minimize linearity errors.
• Provides a complete A/D solution by combining the converter, internal reference, and on-chip clock in a single package.
• Features a high-speed parallel interface allowing direct connection to digital signal processors and microcontrollers.

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems requiring 16-bit precision.
• Industrial control applications utilizing standard ±10 V input ranges.
• Interfaces between analog sensors and microprocessors or DSPs.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade and package suffix against the manufacturer's ordering guide to ensure compatibility with system requirements. Confirm that the 28-lead SSOP footprint matches the design layout. Check for end-of-life status or obsolescence notices prior to finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 200 kSPS throughput with 16-bit resolution. Ensure the design accommodates a single +5 V power supply and provides adequate thermal management for 100 mW dissipation. Verify that the parallel interface timing constraints align with the host processor capabilities.

Analog To Digital Converters (ADC) Part Context

The AD976ACRS belongs to the AD976/AD976A family of BiCMOS A/D converters. This series distinguishes itself through the integration of a switched capacitor architecture and factory-trimmed linearity, offering a compact alternative to discrete ADC solutions. The AC suffix denotes the C-grade performance level within the 200 kSPS variant lineup.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include AD976ABRS and AD976AARS, which share the 200 kSPS throughput and SSOP package but may differ in AC accuracy grades such as S/(N+D) ratios.
