Substitute Part Grouping Explanation

Substitute parts for the DAC8830ICDR are identified based on strict equivalence across the following critical parameters:

• Resolution: 16-bit conversion capability
• Converter Count: Single D/A converter configuration
• Output Specification: Voltage output, unbuffered topology
• Interface Protocol: SPI serial data interface
• Supply Voltage Ranges: Analog supply 2.7V–5.5V; Digital supply 2.7V–5.5V
• Accuracy Metrics: INL/DNL specifications of ±0.5 LSB
• Settling Performance: 1µs typical settling time
• Package Format: 8-SOIC surface mount package (0.154" width, 3.90mm)
• Compliance: ROHS3 compliance and MSL Level 2 rating

The DAC8830IBDR meets all these criteria, establishing it as a parametric equivalent suitable for direct substitution in applications where the DAC8830ICDR is specified.
