This document details the CS4341A DAC's features, including dynamic range, THD+N, power supply, clock jitter sensitivity, line outputs, digital de-emphasis, ATAPI mixing, digital volume control, sample rates, automatic mode detection, and more.
The CS4341A stereo digital‑to‑analog converter provides 24‑bit resolution and supports standard audio sample rates up to 192 kHz. It features a dynamic range of 101 dB, THD+N of –91 dB, on‑chip digital de‑emphasis, a 94 dB digital volume control with 1 dB steps, and low clock‑jitter sensitivity. The device operates from a +3.3 V or +5 V supply and consumes about 50 mW at 3.3 V.
The chip is pin‑compatible with the earlier CS4341, making it a drop‑in upgrade for DVD audio players and similar applications. It includes a typical connection diagram, detailed pin description, register map, and timing diagrams for I²C and SPI control ports. Package options are 16‑pin SOIC (KS) and lead‑free (KSZ) versions, rated for –10 °C to 70 °C operation.
