AD977ACR

Analog To Digital Converters (ADC) Overview

The AD977ACR is a high-speed, low-power 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes a successive approximation architecture with a switched capacitor design and operates from a single 5 V supply. The device dissipates a maximum of 100 mW and features an internal 2.5 V reference alongside a high-speed serial interface. It supports throughput rates up to 200 kSPS and accommodates input ranges including unipolar 0 V–10 V and bipolar ±10 V. Packaged in a 20-lead SOIC, it is specified for industrial temperatures ranging from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Single-supply operation enabled by integrated voltage reference
• Factory-calibrated switched capacitor architecture minimizes linearity errors
• High-speed serial interface simplifies digital connectivity

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise signal digitization
• Data acquisition modules for sensor interfacing
• Battery-powered instrumentation utilizing single-supply constraints

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CRZ' or 'C' against current manufacturer documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as lead times may vary. Ensure the operating temperature range matches the application environment requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select the AD977ACR when a 16-bit resolution and 200 kSPS sampling rate are required within a single 5 V supply constraint. Compare against the AD977 for applications needing lower 100 kSPS throughput. Verify that the serial interface timing aligns with the host processor capabilities and that the SOIC package fits the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD977 family of 16-bit ADCs from Analog Devices. The family includes variants such as the AD977A and AD977BNZ, which share similar architectural foundations but differ in throughput speeds and package styles. The AD977 series is designed for applications balancing precision with power efficiency.

Analog To Digital Converters (ADC) Replacement Considerations

The AD977A is a functional equivalent offering higher throughput. The AD977BNZ provides identical performance in a PDIP package. Verify pin compatibility and software register configurations when substituting these parts.
