AD977ACN

Analog To Digital Converters (ADC) Overview

The AD977ACN is a high-speed, low-power 16-bit analog-to-digital converter manufactured by Analog Devices Inc. It utilizes a successive approximation switched capacitor architecture and operates from a single +5 V supply with a maximum power dissipation of 100 mW. The device features a throughput rate of 200 kSPS and includes an internal 2.5 V reference. It supports serial data interface and on-chip clock generation. Input ranges include unipolar (0 V to 10 V, 0 V to 5 V, 0 V to 4 V) and bipolar (±10 V, ±5 V, ±3.3 V). The component is housed in a 20-lead Skinny DIP package.

Analog To Digital Converters (ADC) Feature Summary

• Factory calibrated switched capacitor architecture minimizes linearity errors
• Single-supply operation reduces system complexity
• Integrated internal voltage reference eliminates external components

Analog To Digital Converters (ADC) Applications

• Data acquisition systems requiring 16-bit resolution
• Industrial process control instrumentation
• Medical equipment signal processing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CN' indicates the 20-lead Skinny DIP package variant. Confirm the manufacturer is Analog Devices Inc. Check RoHS compliance status as indicated in official documentation. Ensure the part number matches the exact 200 kSPS specification for the AD977A variant rather than the standard AD977.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 200 kSPS sampling rate are required within a single 5 V supply design. Consider the internal reference capability if external precision references are undesirable. Verify that the Skinny DIP package fits the target PCB layout constraints compared to SOIC or SSOP alternatives.

Analog To Digital Converters (ADC) Part Context

The AD977ACN belongs to the AD977 family of 16-bit ADCs. It is distinguished from the AD977 by its higher 200 kSPS throughput rate compared to the 100 kSPS rate of the base model. Both variants share the same SAR architecture and pinout compatibility.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes may include other 16-bit SAR ADCs with similar serial interfaces and 200 kSPS rates. Verify pin compatibility and input range specifications before substitution.
