Analog Devices AD1892 Integrated Digital Receiver/Rate Converter Datasheet
The AD1892 combines a fully compatible digital audio receiver (DAR) with an asynchronous sample‑rate converter, supporting EIAJ CP‑340, IEC‑958, AES/EBU and S/PDIF standards. It provides Q‑Channel subcode and Channel Status buffers, a 20‑bit SamplePort® architecture, and a flexible SPI‑compatible serial control interface for microcontroller‑oriented operation.
The device operates from a single +5 V supply, offers a 1:5 up‑sampling range (8 kHz → 48 kHz) and down‑sampling to 44.1 kHz, delivers 120 dB dynamic range with –113 dB THD+N, and is available in a 28‑lead SOIC package suitable for industrial temperature ranges (‑40 °C to +85 °C).
