Replacement verdict
Not a drop-in replacement
The AD5547BRUZ and AD5542AARUZ are not drop-in replacements for each other. Although both are Analog Devices precision DACs sharing a TSSOP-28 style footprint and similar SPI-compatible serial interfaces, they differ fundamentally in architecture, resolution, channel count, and reference configuration. The AD5547BRUZ is a dual-channel 16-bit current-output multiplying DAC, while the AD5542AARUZ is a single-channel 16-bit voltage-output DAC. These differences in output type, channel count, internal reference, and output amplifier integration make direct substitution impractical without significant circuit redesign.
