AD977BRZRL

Analog To Digital Converters (ADC) Overview

The AD977BRZRL is a 16-bit, single-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates with a sampling rate of 100 kSPS and features a serial interface for data output. The device supports single-ended input signals and functions on dual 5 V power supplies for analog and digital sections. 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 operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RL' against official Analog Devices documentation to confirm reel packaging status and any functional differences compared to tube versions. Ensure compatibility with existing PCB footprints for the SOIC-20 package. Check for moisture sensitivity level requirements during assembly. Confirm availability through authorized distributors as supply may be limited.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit resolution and 100 kSPS speed are required for single-ended inputs. Compare with AD977CRZ for package differences or AD977BNZ for through-hole options. Consider the serial interface requirement versus parallel alternatives if pin count is constrained. Verify power supply constraints match the 5 V specification.

Analog To Digital Converters (ADC) Part Context

The AD977 series represents a family of low-power, high-speed ADCs designed for general-purpose applications. The AD977BRZRL belongs to the commercial grade subset, offering balanced performance for cost-sensitive designs. It complements other data converters in the Analog Devices portfolio by providing a simple interface solution for moderate-speed, high-accuracy tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include AD977CRZ and AD977ARZ, which share similar electrical characteristics but may differ in packaging or temperature grades. Cross-reference with AD976A series for potential pin-compatible alternatives with slightly different specifications.
