Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADC08062CIWM/NOPB is evaluated based on the following critical parameters: resolution (8-bit), package form factor (20-SOIC), data interface (parallel), operating temperature range (-40°C to 85°C), and supply voltage compatibility (5V operation). The AD7822BRZ qualifies as a functional substitute based on matching 8-bit resolution, identical package specification, parallel interface, and overlapping operating temperature range. Both components support 5V supply operation and maintain surface-mount compatibility.

Key substitution criteria:

• 8-bit resolution requirement
• 20-SOIC package form factor
• Parallel data interface
• 5V supply voltage operation
• -40°C to 85°C operating temperature range
• Surface-mount technology

Parameter Comparison

Engineering Selection Recommendations

The AD7822BRZ is an active product from Analog Devices Inc. and represents a viable substitute for the obsolete ADC08062CIWM/NOPB. Both components maintain ROHS3 compliance and identical operating temperature specifications. The AD7822BRZ offers enhanced sampling rate capability (2M versus 1.5M samples per second) and extended supply voltage flexibility (2.7V to 3.3V in addition to 5V operation). Both components are packaged in 20-SOIC form factor with surface-mount technology, ensuring mechanical and electrical compatibility in existing PCB layouts.

The primary design consideration is the reduction in input channel count: the AD7822BRZ provides one input channel compared to the ADC08062CIWM/NOPB's two channels. System designs requiring dual-channel simultaneous sampling must account for this architectural difference through multiplexing or additional converter stages.

Frequently Asked Questions (FAQ)

Q: Can the AD7822BRZ directly replace the ADC08062CIWM/NOPB in existing designs?

A: Direct replacement is possible for applications requiring single-channel conversion. The identical 20-SOIC package, parallel interface, and 5V supply operation ensure mechanical and electrical compatibility. Designs utilizing both input channels of the ADC08062CIWM/NOPB require system-level modifications to accommodate the single-input architecture of the AD7822BRZ.

Q: What are the key differences between these two converters?

A: The primary differences are input channel count (2 versus 1), conversion architecture (sigma-delta versus pipelined), and sampling rate (1.5M versus 2M samples per second). The AD7822BRZ supports dual supply voltage ranges (2.7V to 3.3V and 5V), while the ADC08062CIWM/NOPB operates exclusively at 5V.

Q: Are both components RoHS compliant?

A: Yes, both the ADC08062CIWM/NOPB and AD7822BRZ are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the package compatibility between these parts?

A: Both components utilize the 20-SOIC package with identical dimensions (0.295" width, 7.50mm). Surface-mount footprints are mechanically compatible, allowing direct PCB layout reuse without modification.

Q: Why is the ADC08062CIWM/NOPB classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The AD7822BRZ, maintained in active production status, provides continued availability and supply chain reliability for equivalent functionality.
