AD977CRRL

Analog To Digital Converters (ADC) Overview

The AD977CRRL is a 16-bit resolution Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. It utilizes a Successive Approximation Register (SAR) architecture and supports a sampling rate of up to 200 kSPS. The device features a single-ended input configuration and communicates via a serial interface. It operates on a single 5 V supply for both analog and digital domains, with a typical power dissipation of 100 mW. The component is housed in a 20-lead SOIC package and is rated for an industrial operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• High-resolution 16-bit data conversion capability using SAR technology
• Flexible serial interface compatibility for microprocessor integration
• Low-power operation suitable for battery-constrained applications

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring high accuracy
• Industrial process control monitoring
• Medical equipment signal acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RRL' against official Analog Devices documentation to confirm reel packaging and tape specifications. Ensure the part number matches the exact temperature grade and package variant required for your design. Cross-reference with authorized distributors to confirm current availability status as this series may have limited stock or obsolescence notices.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution is mandatory for precision measurement tasks. The 200 kSPS speed is adequate for low-frequency signal conditioning. Compare performance metrics such as SNR and DNL against other SAR ADCs if higher throughput is needed. Verify that the serial interface timing aligns with the host controller's capabilities.

Analog To Digital Converters (ADC) Part Context

The AD977CRRL belongs to the AD977 family of BiCMOS A/D converters from Analog Devices. This family is designed for applications demanding high linearity and low noise. The CRRL designation indicates a specific commercial/industrial temperature range and reel packaging format within the broader AD977 product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include the AD977CRZ and AD977BRZ from Analog Devices, which share similar pinouts and electrical characteristics. Other compatible options may include parts from the AD976 series, though interface and performance differences should be evaluated.
