This document is the product manual of EMA series audio amplifiers, which introduces the characteristics, parameters, application scenarios and other information of EMA series products in detail.
The manual lists the technical parameters of the EMA series audio amplifiers, including working voltage (2.2‑5.5 V), speaker configurations, gain control, PSRR values and output power for each model. Package types such as MSOP‑8, MSOP‑10 and TSSOP‑28FD are also detailed.
For the EMP series low‑voltage linear regulators, the document provides output current, standby current, voltage accuracy, PSRR, thermal protection and package information (e.g., SOT‑23, SOT‑25, MSOP‑8). Additional sections cover battery management ICs and white‑LED driver ICs with efficiency and current specifications. This manual is written in Chinese.
