Electrical Compatibility Requirements:

• Resolution: 12 bits
• Converter Count: 2 D/A converters
• Output Configuration: Voltage output with buffering
• Interface Protocol: SPI
• Reference Input: External reference type
• Supply Voltage Range: 2.7V to 3.6V (both analog and digital)
• Settling Time: 15µs typical
• Linearity: INL/DNL ±1 LSB maximum
• Architecture: R-2R topology

Mechanical Compatibility Requirements:

• Package Type: 16-QSOP / 16-SSOP
• Mounting: Surface mount
• Pin Count: 16 pins

The MAX5155AEEE+ qualifies as a direct substitute based on identical electrical specifications and package compatibility.
