AD1845JP-REEL

Overview

The AD1845JP-REEL is a parallel-port 16-bit SoundPort stereo codec manufactured by Analog Devices Inc. This single-chip integrated circuit combines key audio data conversion and control functions to provide a complete computer audio solution for business and multimedia applications. It supports sample rates from 4.0 kHz to 50 kHz and operates from +5 V supplies. The device features a byte-wide parallel interface compatible with ISA and EISA buses, supporting two DMA channels for full-duplex operation. It includes on-chip capture and playback FIFOs, advanced power-down modes, and programmable gain and attenuation capabilities.

Feature Summary

Integrates stereo codec functionality with mixing and bus drive capability into a single chip
Supports full-duplex operation via dual DMA channels and on-chip FIFOs
Compatible with Microsoft and Windows Sound Systems and MPC Level-2+ standards

Applications

Business audio systems
Multimedia computer applications
ISA and EISA bus-based audio solutions

Procurement Notes

Verify the specific suffix JP against official documentation to confirm package type and tape/reel configuration. Confirm current lifecycle status as legacy components may have limited availability or discontinuation notices. Ensure compatibility with existing ISA/EISA bus architectures before procurement.

Selection Notes

Select this component for legacy parallel-port audio designs requiring 16-bit stereo conversion. Verify pin compatibility with alternatives like AD1848 or CS4248 if board space constraints exist. Ensure system clock derivation matches the required sample rate range of 4.0 kHz to 50 kHz.

Part Context

The AD1845 belongs to the SoundPort series of stereo codecs designed for PC audio integration. It serves as a foundational component for older generation multimedia sound cards and industrial audio interfaces relying on parallel bus communication rather than serial protocols.

Replacement Considerations

Pin-compatible alternatives include the AD1848, AD1846, CS4248, and CS4231. Verify functional equivalence regarding FIFO depth and bus drive capability when substituting.
