Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD7228ACR is determined by strict equivalence across the following critical parameters:

• Resolution and Converter Count: 8-bit resolution with 8 independent D/A converters
• Output Characteristics: Voltage output with buffering capability
• Interface and Architecture: Parallel data interface with R-2R resistor ladder architecture
• Reference Configuration: External reference requirement
• Electrical Performance: Settling time (5µs, 7µs), INL/DNL specifications (±0.5 LSB Max, ±1 LSB Max)
• Supply Voltage Ranges: Analog supply 10.8V ~ 16.5V or ±5V; Digital supply 14.6V ~ 16.5V
• Package Compatibility: 24-SOIC surface mount package with identical physical dimensions
• Temperature Range: -40°C ~ 85°C operating specification

The AD7228ACRZ qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional architecture.

Parameter Comparison

Engineering Selection Recommendations

The AD7228ACRZ is the qualified substitute for the obsolete AD7228ACR. Both components share identical electrical specifications, package configuration, and functional performance characteristics. The primary distinction is product status: the AD7228ACRZ maintains active production and support status, whereas the AD7228ACR is obsolete.

For new designs or system maintenance requiring 8-bit DAC functionality with the specified electrical and physical parameters, the AD7228ACRZ is the appropriate selection. The AD7228ACRZ is ROHS3 compliant and REACH unaffected, providing regulatory compliance for current manufacturing standards.

Both components are classified under ECCN EAR99 and HTSUS 8542.39.0001 for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the AD7228ACRZ directly replace the AD7228ACR in existing designs?

A: Yes. The AD7228ACRZ is electrically and mechanically identical to the AD7228ACR. All electrical specifications, pin configurations, package dimensions, and performance characteristics are equivalent. No circuit modifications are required.

Q: What is the primary reason to substitute the AD7228ACR?

A: The AD7228ACR is classified as obsolete. The AD7228ACRZ provides equivalent functionality with active product status and current manufacturing support.

Q: Are there differences in packaging between these parts?

A: Both components use the 24-SOIC surface mount package with identical physical dimensions (0.295" width, 7.50mm). The AD7228ACRZ is supplied in tube packaging, while the AD7228ACR packaging specification was not provided.

Q: Do these components have the same moisture sensitivity requirements?

A: Yes. Both the AD7228ACR and AD7228ACRZ have MSL rating 3 with a 168-hour floor life specification.

Q: Are there regulatory compliance differences?

A: The AD7228ACRZ is certified as ROHS3 compliant and REACH unaffected. The AD7228ACR compliance status was not specified in the provided data.

Q: What supply voltage configurations do these components support?

A: Both components support dual supply configurations: analog supply of 10.8V ~ 16.5V or ±5V, and digital supply of 14.6V ~ 16.5V.
