EMA2217 Datasheet | Elite MicroPower

Preliminary Elite Micro Power Inc. 2-W STEREO AUDIO POWER AMPLIFIER WITH FOUR SELECTABLE GAIN SETTINGS GENERAL DESCRIPTION The EMA2217 is a stereo audio power amplifier in a 20-pin TSSOP thermally enhanced package Features ．Internal Gain control Which Eliminates External Gain-Setting Resistors ．Fully Differential Configuration ．Low Supply Current (6m A Typical) ．De-pop Citcuitry capable of driving 2W of continuous RMS power per channel into 4Ω loads. Internal gain control minimizes the number of external ponents needed, simplifying the design, and freeing up board space for other Features . Amplifier gain is internally configured and controlled by way of two terminals (G0 and G1). Gain settings of 6 d B, 10 d B, 15.6 d B, and 21.6 d B are provided. EMP products are Pb-free and Ro HS pliant. APPLICATIONS ．Notebook puters, PDAs, and Other Portable Audio devices Elite Micro Power Inc. reserves the right to make changes to improve reliability or manufacturability without notice, and customers are advised to obtain the latest version of relevant information prior to placing orders.
