AD977BRSZ

Analog To Digital Converters (ADC) Overview

The AD977BRSZ 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 features a serial interface for data output and accepts single-ended analog inputs. It operates on a single 5 V supply for both analog and digital domains, with a typical power dissipation of 100 mW. Key performance metrics include an SNR of 85 dB, DNL of +/- 2 LSB, and INL of +/- 3 LSB. It is housed in a 20-lead SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Request original manufacturer datasheets and test reports to confirm specifications match the AD977BRSZ part number. Inspect packaging integrity and pin condition upon receipt. Ensure compliance with RoHS directives if required for your specific manufacturing environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-resolution 16-bit ADC is required with low power constraints. Compare against the AD977CRZ for surface-mount preferences or AD977BNZ for through-hole requirements. Ensure the system design accommodates the 20-SOIC footprint and 5V logic levels. Verify that the serial interface timing meets the host processor's clock requirements.

Analog To Digital Converters (ADC) Part Context

The AD977BRSZ belongs to the AD977 family of BiCMOS A/D converters from Analog Devices. This series is designed for general-purpose applications requiring high accuracy and low power. The 'BR' suffix typically denotes a specific temperature grade or package variant within the broader AD977 product line, sharing core electrical characteristics with other members like the AD977CRZ.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include the AD977CRZ and AD977BNZ, which share identical electrical specifications but differ in package type (SOIC vs. PDIP). Cross-reference with Texas Instruments ADS7809UB for potential alternative sourcing, noting differences in interface or packaging may require schematic adjustments.
