AD977BN

Analog To Digital Converters (ADC) Overview

The AD977BN is a monolithic 16-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a successive approximation register (SAR) architecture with a single-ended input and serial interface. The device operates at a sampling rate of 100 kS/s, powered by a single +5 V supply for both analog and digital sections. Key performance metrics include an 85 dB signal-to-noise ratio (SNR), ±3 LSB integral nonlinearity (INL), and ±2 LSB differential nonlinearity (DNL). It dissipates 100 mW and functions within a temperature range of -40°C to +85°C. The component is housed in a 20-pin PDIP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated SAR ADC core with internal or external reference selection
• Serial data interface compatible with standard microprocessor buses
• Low power consumption optimized for battery-operated systems

Analog To Digital Converters (ADC) Applications

• Industrial process control monitoring
• Portable instrumentation
• Data acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BN' indicates the through-hole PDIP-20 package variant distinct from surface-mount versions. Confirm RoHS compliance status via the manufacturer datasheet as legacy parts may have varying environmental declarations. Check current lifecycle status as this model may be discontinued or subject to limited availability constraints.

Analog To Digital Converters (ADC) Selection Notes

Select the AD977BN when a 16-bit resolution and 100 kS/s throughput are required in a through-hole configuration. Ensure the application supports single-ended inputs and requires a serial interface. Compare against the AD977CRZ if a surface-mount SOIC-20 package is preferred instead of the PDIP form factor.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD977 series of high-resolution data converters. It shares architectural similarities with other members like the AD977CRZ but differs in packaging and potentially pinout compatibility due to the through-hole design. It serves as a precision conversion solution for applications requiring moderate speed and high accuracy.

Analog To Digital Converters (ADC) Replacement Considerations

The AD977CRZ is a direct functional equivalent offering identical electrical specifications but utilizes a surface-mount SOIC-20 package. Verify mechanical fit and soldering requirements before substitution.
