MXT8234 is a perfect stereo digital-to-analog output system, which integrates interpolation, 1-bit D/A conversion and analog output filtering in an 8-pin package. MXT8234 supports mainstream audio data interface formats, and different devices are distinguished only by the types of interfaces they support.
The MXT8234 is a 24‑bit, 96 kHz stereo digital‑to‑analog converter presented in an 8‑lead package. It integrates a delta‑sigma modulator, digital de‑emphasis, and on‑chip low‑pass filtering, supporting common audio interfaces such as DVD, SVCD and A/V receivers.
The device operates in two modes: a base‑rate mode (BRM) with MCLK/LRCK ratios of 256, 384 or 512, and a high‑rate mode (HRM) with ratios of 128 or 192, allowing sampling rates up to 96 kHz. Detailed pin functions, power specifications, and package dimensions are provided. This manual is written in Chinese.
