Substitute Part Grouping Explanation

Substitution of the AD7228ABN 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-buffered output with external reference
• Interface Protocol: Parallel data interface
• Electrical Performance: Settling time (5µs, 7µs), INL/DNL (±1 LSB Max), R-2R architecture
• Supply Voltage Ranges: Analog supply 10.8V ~ 16.5V, ±5V; Digital supply 14.6V ~ 16.5V
• Package Specification: 24-pin DIP package (0.300", 7.62mm pitch)
• Thermal Range: Operating temperature -40°C ~ 85°C
• Mounting Technology: Through-hole configuration

The AD7228ABNZ is identified as a direct substitute based on identical electrical specifications, performance characteristics, and package configuration. The primary distinction is product status and packaging format.
