AD977ANZ

Analog To Digital Converters (ADC) Overview

The AD977ANZ is a 16-bit, single-channel Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. It utilizes a Successive Approximation Register (SAR) architecture and supports sampling rates of 100 kSPS or 200 kSPS. The device operates on a single 5 V supply for both analog and digital domains. It features a serial interface compatible with SPI standards and accepts single-ended voltage inputs. The component is housed in a 20-pin PDIP package and is rated for an operating temperature range from -40°C to +85°C. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 85 dB, Integral Nonlinearity (INL) of ±3 LSB, and Differential Nonlinearity (DNL) of ±2 LSB.

Analog To Digital Converters (ADC) Feature Summary

• High-resolution 16-bit conversion capability using SAR architecture
• Flexible sampling rate selection between 100 kSPS and 200 kSPS
• Single-supply 5 V operation simplifying power design
• Serial data interface compatible with standard microcontroller protocols

Analog To Digital Converters (ADC) Applications

• Precision industrial process control systems
• Battery-powered instrumentation requiring low power consumption
• Data acquisition modules for environmental monitoring
• Medical diagnostic equipment requiring high resolution

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ANZ' to confirm lead-free compliance and packaging type. Confirm the required sampling speed setting (100 kSPS vs 200 kSPS) matches the application timing requirements. Ensure the single-ended input configuration aligns with the sensor output type before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit resolution is mandatory for low-frequency signals. Compare against the AD976 series if dual-channel functionality is needed instead of single-channel. Consider the PDIP package constraints for PCB layout if surface-mount alternatives like the CRZ variant are not suitable for the assembly process.

Analog To Digital Converters (ADC) Part Context

The AD977ANZ belongs to the AD977 family of BiCMOS ADCs from Analog Devices. This family includes variants such as the AD977CRZ and AD977BRZ, which share identical electrical specifications but differ in packaging and temperature grades. The AD977 series is designed for applications demanding high accuracy at moderate speeds.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes include the AD977CRZ and AD977BRZ. Verify that the alternative package type meets mechanical constraints. Cross-reference with the AD976 series if channel count differences are acceptable.
