Product details

The AD1847JP is a 16-bit Stereo Audio codec from the AD1847 series, integrating two ADCs and two DACs with a Sigma-Delta modulator topology. Data interface supports both Parallel and Serial modes.

Supply rails and temperature grade – fit check

Analog and digital supplies both run from 4.75V to 5.25V — a single 5V rail can power the entire codec, simplifying the power tree. Dynamic range is specified at 70 dB typ for the ADC path and 76 dB typ for the DAC path.

Package and mounting – rework and footprint notes

Housed in a 44-lead PLCC with J-leads (44-PLCC, 16.59x16.59 mm body). The J-lead footprint is surface-mount but does not require the fine-pitch stencil of a QFP — a standard PLCC socket or solder paste profile works. RoHS non-compliant — the part contains lead in the solder finish. If your assembly line is RoHS-exempt (industrial / medical / military), this is fine; for consumer RoHS-mandated production, a Pb-free equivalent would need to be sourced.

Lifecycle and sourcing – active but niche

However, it is a legacy part from the SoundComm era; volume may be low, and lead times can stretch. The AD1847 series has few direct cross-shoppers — the 44-PLCC footprint and 5V-only supply are increasingly uncommon in modern audio codecs.

Frequently asked questions

How can I order AD1847JP or check availability?

The AD1847JP is Active per Analog Devices, so it remains orderable through distribution. We source it per RFQ — submit your target quantity and we will confirm current pricing and lead time from our supply chain. No stock-holding claim on this page.

What is the AD1847JP replacement or equivalent?

No official replacement or pin-compatible equivalent is documented for the AD1847JP. The 44-PLCC package and 5V-only analog/digital supply rails are uncommon in newer codecs. For a new design, evaluate a modern 24-bit codec in a smaller package (e.g., TQFP or QFN) with 3.3V operation, but that will require a PCB layout change.

What package does AD1847JP use?

44-lead PLCC with J-leads, body size 16.59x16.59 mm. The supplier device package is designated 44-PLCC. Surface-mount, but the J-lead form factor allows socketing or standard reflow.
