Substitute Part Grouping Explanation

Substitution of the AD5452YRM is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion capability
• Channel Configuration: Single D/A converter
• Output Architecture: Current-mode unbuffered output
• Interface Protocol: SPI and DSP compatibility
• Supply Voltage Range: 2.5V to 5.5V for both analog and digital supplies
• Linearity Specifications: INL/DNL performance of ±0.5 LSB (Max) and ±1 LSB (Max)
• Settling Time: 110ns maximum
• Package Compatibility: 8-MSOP surface mount form factor
• Temperature Range: -40°C to 125°C operation

The AD5452YRMZ qualifies as a direct substitute based on identical electrical specifications, package geometry, and functional performance across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The AD5452YRMZ is the direct equivalent substitute for the AD5452YRM. Both parts share identical electrical specifications, functional performance, and physical packaging. The primary distinction is product lifecycle status: the AD5452YRM is obsolete, while the AD5452YRMZ maintains active production status.

The AD5452YRMZ provides additional compliance certifications including ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to environmental and regulatory requirements. For new designs or system maintenance requiring long-term component availability, the AD5452YRMZ is the appropriate selection.
