Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC8248FSZ are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Resolution: 12-bit conversion
• Channel Count: Dual D/A converters (2 channels)
• Output Configuration: Current output, unbuffered topology
• Data Interface: Parallel input
• Reference Input: External reference requirement
• Supply Voltage Ranges: Analog 5V ~ 15V, Digital 5V ~ 15V
• Settling Time: 1µs maximum
• Linearity Specifications: INL/DNL ±1 (Max), ±4 (Max)
• Architecture: R-2R ladder network
• Temperature Range: -40°C ~ 85°C
• Package: 24-SOIC form factor with identical physical dimensions
• Compliance: RoHS3 and REACH requirements

The DAC8222FSZ meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the DAC8248FSZ and DAC8222FSZ maintain active product status with identical compliance certifications. Both components are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications. The parts are functionally interchangeable at the electrical and mechanical level, with identical pinout compatibility in 24-SOIC surface-mount packages. Selection between these parts should be based on availability, lead time, and cost considerations, as no technical differentiation exists between them.
